碧云天细胞自噬染色检测试剂盒(MDC法)说明书
细胞自噬染色检测试剂盒(MDC 法)产品简介:碧云天生产的细胞自噬染色检测试剂盒(MDC 法),即Autophagy Staining Assay Kit with MDC ,是一种使用丹酰尸胺,也称单丹磺酰尸胺、丹酰尸胺或丹酰戊二胺(monodansylcadaverine, MDC)作为荧光探针快速便捷地检测细胞自噬的试剂盒。
自噬(autophagy)是一种在进化上高度保守的通过溶酶体吞噬并降解部分自身组分的细胞内分解代谢途径。
自噬与多种生理功能有关,在饥饿等环境条件下,细胞通过自噬降解多余或异常的细胞内组分,为细胞的生存提供能量及原材料,促进生物体的生长发育、细胞分化及对环境变化产生应答。
自噬异常与多种病理过程如肿瘤、神经退行性疾病、代谢疾病、病原体感染等都有密切关系。
由于细胞自噬在生理和病理过程中都有重要作用,自噬已经成为细胞生物学领域的一个研究热点。
MDC 是细胞自噬检测最常用的荧光探针之一。
MDC 可以通过离子捕获(ion trapping)和与膜脂的特异性结合,从而特异性标记自噬体(autophagosome),也称autophagic vacuole ,因而常用于细胞自噬的检测。
MDC 是一种嗜酸性荧光探针,很多酸性膜性结构也会被MDC 染色,因此MDC 染色时正常的细胞也会有一定的染色背景。
本产品的染色原理决定了本产品只能用于培养的细胞或者组织的细胞自噬荧光染色检测,不能用于冻存的或固定的细胞、组织或者组织切片的染色检测。
使用本产品染色后可以通过荧光显微镜拍照观察,也可以通过荧光酶标仪或流式细胞仪进行荧光检测。
荧光显微镜观察时可以使用紫外区激发光激发,发出绿色荧光。
荧光酶标仪或流式细胞仪推荐的激发波长为335nm (330-360nm 均可),发射波长为512nm (510-540nm 均可)。

Trigonox B(滴苷但羊水)产品数据表单说明书
Product Data SheetTrigonox BDi-tert-butyl peroxideTrigonox® B is a pure peroxide in liquid form.CAS number110-05-4EINECS/ELINCS No. 203-733-6TSCA statuslisted on inventory Molecular weight 146.2Active oxygen contentperoxide10.94%SpecificationsAppearance Clear liquidAssay≥ 99.0 %ApplicationsTrigonox® B (Di-tert-butyl peroxide) can be used for the market segments: polymer production, polymer crosslinking and acrylics production with their different applications/functions. For more information please check our website and/or contact us.Half-life dataThe reactivity of an organic peroxide is usually given by its half-life (t½) at various temperatures. For Trigonox® B in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:0.1 hr at 164°C (327°F)1 hr at 141°C (286°F)10 hr at 121°C (250°F)Formula 1kd = A·e-Ea/RTFormula 2t½ = (ln2)/kdEa153.46 kJ/moleA 4.20E+15 s-1R8.3142 J/mole·KT(273.15+°C) KThermal stabilityOrganic peroxides are thermally unstable substances which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used for transport is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT80°C (176°F)Method The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria - United Nations, NewYork and Geneva).StorageDue to the relatively unstable nature of organic peroxides, a loss of quality will occur over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts Max.40°C (104°F) andTs Min.-30°C (-22°F) to prevent crystallizationNote When stored according to these recommended storage conditions, Trigonox® Bwill remain within the Nouryon specifications for a period of at least 6 months afterdelivery.Packaging and transportIn North America Trigonox® B is packed in non-returnable, five gallon polyethylene containers of 30 lb net weight and steel drums of 100 or 340 lb net weight. In other regions the standard packaging is a 30-liter HDPE can (Nourytainer®) for 20 kg peroxide. Delivery in a 200 l steel drum for 150 kg peroxide is also possible in a number of countries. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Nouryon representative. Trigonox® B is classified as Organic peroxide type E; liquid, Division 5. 2; UN 3107.Safety and handlingKeep containers tightly closed. Store and handle Trigonox® B in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room.

让您的WB实验多姿多彩
蛋白免疫印迹实验(Western Blot)实验大家肯定都不陌生,要想做出好看的条带,从制胶开始就不容半点马虎。
WB制胶可谓实验室新手的必修课了,想想小编我在当初实验室的时候,就没少帮师兄师姐配置WB凝胶,泛黄的配方表小编还记忆犹新。
WB凝胶配
方表
说起WB凝胶配置,小编可有一肚子苦水要倒,第一个让人头疼的一点就是多种溶液都需要计算量取,每次调移液器就要调半天。
还有各种试剂的保存条件也不一样,配胶之前还需要从冰箱,室温柜子里分别拿出不同的溶液。
这还不算,最容易出问题的促凝剂APS,需要新鲜配置,4度保存不能超过一周,关键是粉末还特容易吸水,打开后需要密封保存。
小编之前就踩过一次坑,APS粉末吸水结块,称量配置后的APS含量不够,凝胶凝结不好,整个WB实验条带跑的七扭八歪。

Incucyte
Product Information Presentation, Storage and StabilityThe Incucyte® Fabfluor-pH Antibody Labeling Reagents for antibody internalization are supplied as lyophilized solids in sufficient quantity to label 50 μg of test antibody, when used at the suggested molar ratio (1:3 of test antibody to labeling Fab). The lyophilized solid can be stored at 2-8° C for one year. Once re-hydrated, any unused reagent should be aliquoted and stored at -80° C for up to one year. Avoid repeated freeze-thaw cycles.Incucyte® Fabfluor-pH Antibody Labeling ReagentsFor Antibody Internalization AssaysAntibody Labeling Reagent Rehydrated: -80° C *Excitation and Emission maxima were determined at a pH of 4.5.Fabfluor_quick_guideBackgroundIncucyte ® Fabfluor-pH Antibody Labeling Reagents are designed for quick, easy labeling of Fc-containing test antibodies with a Fab fragment-conjugated pH-sensitive fluorophore. The pH-sensitive dye based system exploits the acidic environment of the lysosomes to quantify in-ternalization of the labeled antibody. As Fabfluor labeled antibodies reside in the neutral extracellular solution (pH 7.4), they interact with cell surface specific antigens and are internalized. Once in the lysosomes, they enter an acidic environment (pH 4.5–5.5) and a substantial in-crease in fluorescence is observed. In the absence of ex-pression of the specific antigen, no internalization occurs and the fluorescence intensity of the labeled antibodies remains low. With the Incucyte ® integrated analysis soft-ware, background fluorescence is minimized. These reagents have been validated for use with a number of different antibodies in a range of cell types. The Incucyte ® Live-Cell Analysis System enables real-time, kinetic eval -uation of antibody internalization.Recommended UseWe recommend that the Incucyte ® Fabfluor-pH Antibody Labeling Reagents are prepared at a stock concentration of 0.5 mg/mL by the addition of 100 μL of sterile water and triturated (centrifuge if solution not clear). The reagent may then be diluted directly into the labeling mixture with test antibody. Do NOT sonicate the solution.Additional InformationThe Fab antibody was purified from antisera by a combination of papain digestion and immunoaffinity chromatography using antigens coupled to agarose beads. Fc fragments and whole IgG molecules have been removed.Human Red (Cat. No. 4722) or Human Orange (Cat. No. 4812)—Based on immunoelectrophoresis and/ or ELISA, the antibody reacts with the Fc portion of human IgG heavy chain but not the Fab portion of human IgG. No antibody was detected against human IgM, IgA or against non-immunoglobulin serum proteins. The anti-body may cross-react with other immunoglobulins from other species.Mouse IgG1 (Cat. No. 4723), IgG2a (Cat. No. 4750) or IgG2b (Cat. No. 4751)—Based on antigen-binding assay and/or ELISA, the antibody reacts with the Fc portion of mouse IgG, IgG2a or IgG2b, respectively, but not the Fab portion of mouse immunoglobulins. No antibody was detected against mouse IgM or against non–immunoglobulin serum proteins. The antibody may cross-react with other mouse IgG subclasses or with immunoglobulins from other species.Rat (Cat. No. 4737)—Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the Fc portion of rat IgG heavy chain but not the Fab portion of rat IgG. No antibody was detected against rat IgM, IgA or against non-immunoglobulin serum proteins. The antibody may cross-react with other immunoglobulins from other species.A.B.C.D.R e d O b j e c t A r e a (x 105 μm 2 p e r w e l l )Time (hours)A U C x 106 (0–12 h )log [α–CD71] (g/mL)Example DataFigure 1: Concentration-dependent increase in antibody internalization of Incucyte ® Fabfluor labeled-α-CD71 in HT1080 cells. α-CD71 and mouse IgG1 isotype control were labeled with Incucyte ® Mouse IgG1 Fabfluor-pH Red Antibody Labeling Reagent.

Seed target cells of interest1.1 Harvest cells of interest and determine cell concentra-tion (e.g. trypan blue + hemocytometer).1.2 Prepare cell seeding stock in target cell growth mediawith a cell density to achieve 40–50% confluence be-fore the addition of labeled antibodies. The suggested starting range is 5,000–30,000 cells/well, although the seeding density will need to be optimized for each cell type.Note: For non-adherent cell types, a well coating may be required to maintain even cell distribution in the well. For a 96-well flat bottom plate, we recommend coating with 50 μL of either 0.01% Poly-L-Or-nithine (PLO) solution or 5 μg/mL fibronectin diluted in 0.1% BSA.Coat plates for 1 hour at ambient temperature, remove solution from wells and then allow the plates to dry for 30-60 minutes prior to cell addition.1.3 Using a multi-channel pipette, seed cells (50 µL perwell) into a 96-well flat bottom microplate. Lightly tapplate side to ensure even liquid distribution in well. Toensure uniform distribution of cells in each well, allowthe covered plate sit on a level surface undisturbed at room temperature in the tissue culture hood for 30minutes. After cells are settled, place the plate insidethe Incucyte® Live-Cell Analysis System to monitor cell confluence.Note: Depending on cell type, plates can be used in assay once cells have adhered to plastic and achieved normal cell morphology e.g.2-3 hours for HT1080 or 1-2 hours for non-adherent cell types. Some cell types may require overnight incubation.2. Label Test Antibody2.1 Rehydrate the Incucyte® Fabfluor-pH Antibody Label-ing Reagent with 100 µL sterile water to result in a final concentration of 0.5 mg/mL. Triturate to mix (centrifuge if solution is not clear).Note: The reagent is light sensitive and should be protected fromlight. Rehydrated reagent can be aliquoted into amber or foilwrapped tubes and stored at -80° C for up to 1 year (avoid freezing and thawing).2.2 Mix test antibody with rehydrated Incucyte® Fabfluor–pH Antibody Labeling Reagent and target cell growth media in a black round bottom microplate or ambertube to protect from light (50 µL/well).a. Add test antibody and Incucyte® Fabfluor–pH Anti-body Labeling Reagent at 2X the final concentration.We suggest optimizing the assay by starting with afinal concentration of 4 µg/mL of test antibody or theFabfluor-pH Antibody Labeling Reagent (i.e. 2Xworking concentration = 8 µg/mL).Note: A 1:3 molar ratio of test antibody to Incucyte® Fabfluor-pHAntibody Labeling Reagent is recommended. The labeling re-agent is a third of the size of a standard antibody (50 and 150KDa, respectively). Therefore, labeling equal quantities will pro-duce a 1:3 molar ratio of test antibody to labeling Fab.b. Make sufficient volume of 2X labeling solution for50 µL/well for each sample. Triturate to mix.c. Incubate at 37° C for 15 minutes protected from light.Note: If performing a range of concentrations of test antibody,e.g. concentration response-curve, it is recommended to createthe dilution series post the conjugation step to ensure consistentmolar ratio. We strongly recommend the use of both a negativeand positive control antibody in the same plate.3. Add labeled antibody to cells3.1 Remove cell plate from incubator.3.2 Using a multi-channel pipette, add 50 µL of 2X labeledantibody and control solutions to designated wells.Remove any bubbles and immediately place plate in the Incucyte® Live-Cell Analysis System and start scanning.Note: To reduce the risk of condensation formation on the lid priorto first image acquisition, maintain all reagents at 37° C prior toplate addition.4. Acquire images and analyze4.1 In the Incucyte® Software, schedule to image every15-30 minutes, depending on the speed of the specific antibody internalization.a Scan on schedule, standard. If the Incucyte® Cell-by-Cell Analysis Software Module (Cat. No. 9600-0031)is available, adherent cell-by-cell or non-adherentcell-by-cell scan types can be selected.b Channel selection: select “phase” and “red” or“phase” and "orange” (depending on reagent used).c Objective: 10X or 20X depending on cell types used,generally 10X is recommended for adherent cells,and 20X for non-adherent or smaller cells.NOTE: The optional Incucyte® Cell-by-Cell Analysis SoftwareModule enables the classification of cells into sub-populationsbased on properties including fluorescence intensity, size andshape. For further details on this analysis module and its appli-cation, please see: /cell-by-cell.4.2 To generate the metrics, user must create an AnalysisDefinition suited to the cell type, assay conditions andmagnification selected.4.3 Select images from a well containing a positiveinternalization signal and an isotype control well(negative signal) at a time point where internalizationis visible.4.4 In the Analysis Definition:Basic Analyzer:a. Set up the mask for the phase confluence measurewith fluorescence channel turned off.b. Once the phase mask is determined, turn the fluores-cence channel on: Exclude background fluorescencefrom the mask using the background subtractionfeature. The feature “Top-Hat” will subtract localbackground from brightly fluorescent objects withina given radius; this is a useful tool for analyzing ob-jects which change in fluorescence intensity overtime.i The radius chosen should reflect the size of thefluorescent object but contain enough backgroundto reliably estimate background fluorescence inthe image; 20-30 μm is often a useful startingpoint.ii The threshold chosen will ensure that objectsbelow a fluorescence threshold will not bemasked.iii Choose a threshold in which red or orange objectsare masked in the positive response image but lownumbers in the isotype control, negative responsewell. For a very sensitive measurement, for example,if interested in early responses, we suggest athreshold of 0.2.NOTE: The Adaptive feature can be used for analysis but maynot be as sensitive and may miss early responses. If interestedin rate of response, Top-Hat may be preferable.Cell-by-Cell (if available):a. Create a Cell-by-Cell mask following the softwaremanual.b. There is no need to separate phase and fluorescencemasks. The default setting of Top-Hat No Mask forthe fluorescence channel will enable backgroundsubtraction without generation of a mask. Ensurethat the Top-Hat radius is set to a value higher thanthe radius of the larger clusters to avoid excess back-ground subtraction.c. The threshold of fluorescence can be determined inCell-by-Cell Classification.Specifications subject to change without notice.© 2020. All rights reserved.

CytoSelect 24 -Well Anoikis Assay 说明书
Product ManualCytoSelect™ 24-Well Anoikis AssayCatalog NumberCBA-080 24 assaysFOR RESEARCH USE ONLYNot for use in diagnostic proceduresIntroductionAdhesion to the extracellular matrix (ECM) is essential for survival and propagation of many adherent cells. Apoptosis that results from the loss of cell adhesion to the ECM, or inappropriate adhesion is defined as “anoikis”. Anoikis, from the Greek word for homelessness, is involved in the physiological processes of tissue renewal and cell homeostasis.A common feature of carcinoma development and growth is the ability of transformed cells to survive under “anchorage independent” or “spheroid” growth conditions. This resistance to anoikis has been shown to be involved in the loss of cell homeostasis, cancer growth, and metastasis. The inhibition of cell adhesion, spreading, and growth on the ECM is an impediment to the cellular healing process, thus making it a possible therapeutic target. Preventing anoikis and enhancing cell adhesion and spreading is a major goal in the development of cell transplantation techniques, including the therapeutic use of progenitor cells. Further studies aimed at controlling the molecular mechanisms of anoikis resistance will serve to define effective therapies for the treatment of many human malignancies.The CytoSelect™ 24-well Anoikis Assay Kit provides a colorimetric and fluorometric format to measure anchorage-independent growth and monitoring anoikis propelled cell death. The kit contains sufficient reagents for the assay of 24 samples in a Poly-Hema coated 24-well plate. Live cells are detected with MTT or Calcein AM. Cell death is detected with the Ethidium Homodimer (EthD-1). Assay PrincipleCells are cultured in poly-Hema coated plate or control plate. Cell viability is determined by MTT or Calcein AM. Anoikis propelled cell death is measured by Ethidium Homodimer (EthD-1). EthD-1 is an excellent marker for measuring dead cells. EthD-1 is a red fluorescent dye that can only penetrate damaged cell membranes. EthD-1 will fluoresce with a 40-fold enhancement upon binding ssDNA, dsDNA, RNA, oligonucleotides, and triplex DNA. Background fluorescence levels are very low because the dyes are virtually non-fluorescent before interacting with cells.Related Products1.CBA-081: CytoSelect™ 96-Well Anoikis Assay2.CBA-230: Cellular Senescence Detection Kit (SA-β-Gal Staining)3.CBA-231: 96-Well Cellular Senescence Assay (SA β-Gal Activity)4.CBA-232: Quantitative Cellular Senescence Assay (SA β-Gal)5.CBA-240: CytoSelect™ Cell Vi ability and Cytotoxicity AssayKit Components1.Anchorage Resistant Plate (Part No. 108001): One 24-well Poly-Hema coated plate.2.Calcein AM (500X) (Part No. 108002): One vial – 50 µL in DMSO.3.Ethidium Homodimer (EthD-1) (500X) (Part No. 108003): One vial – 50 µL.4.Detergent Solution (Part No. 108004): One bottle – 25.0 mL.5.MTT Solution (Part No. 113502): Three tubes – 1.0 mL each.Materials Not Supplied1.Cells for measuring anoikis2.Cell culture medium3.Inverted fluorescence/light microscope4.Fluorometer capable of reading Calcein AM (485 nm/515 nm) and EthD-1 (525 nm/590 nm)fluorescence.StorageStore the Calcein AM and Ethidium Homodimer at -20ºC.

黄连素抑制GRP78表达促进三阴乳腺癌细胞凋亡的研究
黄连素抑制GRP78表达促进三阴乳腺癌细胞凋亡的研究赵虹;沃立科;胡袁媛;王安妮;卢德赵【摘要】[目的]通过检测黄连素对三阴乳腺癌(triple-negative breast cancer,TNBC)细胞株MDA-MB-231细胞凋亡及葡萄糖调节蛋白78(glucose regulated protein 78,GRP78)表达的影响,探讨黄连素抗TNBC的机制.[方法]以MTT法检测不同浓度黄连素对MDA-MB-231细胞增殖的影响,筛选黄连素的处理浓度.将MDA-MB-231细胞分为对照组、40μmol·L-1黄连素组、60μmol·L-1黄连素组、免疫球蛋白重链结合蛋白诱导剂X(immunoglobulin heavy chain binding protein inducer X,BiX)组,以及BiX联合40μmol·L-1黄连素组、BiX联合60μmol·L-1黄连素组.相应药物处理24h后,应用流式细胞术检测细胞凋亡情况,并以Western blot检测细胞GRP78和凋亡相关基因Bcl-2、Bax的表达.[结果]40μmol·L-1以上浓度的黄连素可剂量依赖性抑制MDA-MB-231细胞增殖.与对照组比较,BiX组细胞凋亡率降低(P<0.05)、GRP78和Bcl-2表达增高(P<0.01,P<0.001)、Bax表达减低(P<0.05).与BiX组比较,BiX联合40、60μmol·L-1黄连素组细胞凋亡率增加(P<0.01),GRP78和Bcl-2表达减低(P<0.01,P<0.01),Bax表达增加(P<0.01).[结论]黄连素可以促进MDA-MB-231细胞凋亡,其机制可能是通过下调GRP78的表达,从而降低Bcl-2表达,并促进Bax的表达.【期刊名称】《浙江中医药大学学报》【年(卷),期】2019(043)005【总页数】6页(P407-412)【关键词】三阴乳腺癌;黄连素;葡萄糖调节蛋白78;细胞凋亡;细胞增殖;免疫球蛋白重链结合蛋白诱导剂X【作者】赵虹;沃立科;胡袁媛;王安妮;卢德赵【作者单位】浙江中医药大学附属第一医院杭州 310006;浙江中医药大学附属第一医院杭州 310006;浙江中医药大学附属第一医院杭州 310006;浙江中医药大学附属第一医院杭州 310006;浙江中医药大学生命科学学院【正文语种】中文【中图分类】R331乳腺癌的发病率逐年上升,目前已占据女性恶性肿瘤的首位,病死率仅次于肺癌[1],其中三阴乳腺癌(triple-negative breast cancer,TNBC)是一类雌激素受体(estrogen receptor,ER)、孕激素受体(progesterone receptor,PR)以及人表皮生长因子受体-2(human epidermal growth factor receptors-2,HER-2)均为阴性的乳腺癌,其发病率占乳腺癌总发病率的15%~25%。

General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.Reaction Conditions24 h-96 hApplications Birinapant causes a significant degradation of cIAP1 and 2, which was not enhanced by the addition of TRAIL. Birinapant is also more effective in increasing TRAIL potency than GT13402 in SUM149. In addition, Birinapant markedly decreases the viability of SUM190 cells in a dose-dependent manner.Animal experiment [2]:Animal models Melanoma tumor xenotransplantation mice Dosage form Intra-peritoneal; 30mg/kgPreparation method Dissolved in 12.5% Captisol in distilled water.Applications Compared to vehicle control, cIAP1 protein is reduced to low levels at 3h post and this effect is sustained for 24 hours in the Birinapant treated mice. Staining for activated caspase-3 in biopsies of the same tumors shows a modest increase in apoptotic cells in the Birinapant treated mice compared to vehicle control, 24h post treatment.Other notes Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.References:1. Allensworth JL, Sauer SJ, Lyerly HK et al.

Clin Cancer Res. 2013 Apr 1;19(7):1784-94. BackgroundBirinapant, also called TL32711, is a potent antagonist for XIAP with Kd value of 45 nM and cIAP1 with Kd value <1 nM [1].Birinapant not only binds to the isolated BIR3 domains of cIAP1, cIAP2, XIAP but the single BIR domain of ML-IAP with high affinity and degrades TRAF2-bound cIAP1 and cIAP2 rapidly accordingly inhibiting the activation of TNF-mediated NF- kB. Additionally, birinapantcan promote the formation of caspase-8: RIPK1 complex in response to TNF stimulation, which result in downstreamProduct Data Sheetcaspasesactivation [4].In the inorganic SUM149- and SUM190-derived cells, which with differential XIAP expression (SUM149 wtXIAP, SUM190 shXIAP) and other high cIAP1/2 but low XIAP binding affinity bivalent Smac mimetic GT13402, XIAP inhibition are needed for increasing TRAIL potency. Opposite, single agent efficacy of Birinapant is owing to pan-IAP antagonism. Rapid cIAP1 degradation was caused by birinapant, as well as NF-κB activation, PARP cleavage andcaspase activation. While combined withTNF-α, showing strong combination activity, the combination was more effective than individual. The response in spheroid models was conserved, whereas in vivo birinapant inhibited tumor growth without adding TNF-α in vitro to resistant cell lines. In a parental cell line, TNF-αcombined withbirinapantinhibited the growth of a melanoma cell line with acquired resistance to the same extent of BRAF inhibition [1, 2]. Drug treatment increased the mean [18F]ICMT-11 tumor uptake with a peak at 24 hours for CPA (40 mg/kg; AUC40-60: 8.04 ± 1.33 and 16.05 ± 3.35 %ID/mL × min at baseline and 24 hours, respectively) and 6 hours for birinapant (15 mg/kg; AUC40-60: 20.29 ± 0.82 and 31.07 ± 5.66 %ID/mL × min, at baseline and 6 hours, respectively). Voxel-based spatiotemporal analysis of tumor-intrinsic heterogeneity showed that [18F] ICMT-11 could detect the discrete pockets of caspase-3 activation. Caspase-3 activation that measured ex vivo associated with the increased tumor [18F] ICMT-11, and early radiotracer uptake predicted apoptosis, distinct from the glucose metabolism with [18F]fluorodeoxyglucose-PET, which depicted the continuous loss of cell viability [3].References:1.Allensworth JL, Sauer S, Lyerly HK, et al.

Mechanisms: Pathways:GPCR/G protein; Target:Histamine Receptor Biological Activity: Bilastine is a selective histamine H1 receptor antagonist used for treatment of allergic rhinoconjunctivitis and urticaria. Target: Histamine H1 Receptor Bilastine binds to histamine H1-receptors as indicated by its displacement of [3H]-pyrilamine from H1-receptors expressed in guinea-pig cerebellum and human embryonic kidney (HEK) cell lines. The studies conducted on guinea-pig smooth muscle demonstrated the capability of bilastine to antagonise H1-receptors. Bilastine is selective for histamine H1-receptors as shown in receptorbinding screening conducted to determine the binding capacity of bilastine to 30 different receptors [1]. [ ] Bilastine distribution has an apparent pp volume of distribution of 1.29 L/kg, g and has an elimination half-life of 14.5 h and plasma protein binding of 84-90% [2]. ...
