HSF1A_DataSheet_MedChemExpress

HSF1A_DataSheet_MedChemExpress

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:HSF1A is a cell–permeable activator of heat shock transcription factor 1 (HSF1).IC50 & Target: HSF1[1]In Vitro: HSF1A protects cells from stress–induced apoptosis, binds TRiC subunits and inhibits TRiC activity without perturbation of ATP hydrolysis. Genetic inactivation or depletion of the TRiC complex results in human HSF1 activation and HSF1A inhibits the direct interaction between purified TRiC and HSF1 in vitro. Moreover, fluorescence anisotropy experiments using FITC coupled to HSF1A demonstrates that HSF1A–FITC binds to a purified Tcp1 subunit of TRiC with an affinity of approximately 600 nM. This is validated qualitatively via titration of purified Tcp1 into binding reactions containing 500 nM Biotin or HSF1A–Biotin [1]. Quantification bycounting the number of cell containing aggregates as a function of the total number of cells reveals that at HSF1A concentrations as low as 2 μM, a reduced number of aggregate–containing cells are observed. The fraction of cells containing aggregates continued to decrease in a dose–dependent manner such that pretreatment with 12 μM HSF1A resulta in ~20% of the cells exhibiting aggregates visible by fluorescence microscopy [2].In Vivo: HSF1A enhances HSF1 activity, stabilizes HSF1 expression and minimizes Doxorubicin (DOX)–induced cardiac damage. WKY rats are challenged with DOX (accumulated dose: 30 mg/kgw), and DOX combined with HSF1A (100 mg/kgw/day). Supplementation with HSF1A significantly elevates cardiac functions back to the levels of the control group. HSF1A has been shown to stimulate human HSF1 nuclear translocation, elevate protein chaperone expression and ameliorate protein misfolding and cell death in aneurodegenerative disease model. The echocardiographic results show that HSF1A also alleviates DOX–induced failures in cardiac function [3].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]Protein extracts are generated from mammalian, yeast and E. coli cultures using biotin–binding buffer (20 mM HEPES,5 mM MgCl 2, 1 mM EDTA, 100 mM KCl, 0.03% NP–40) supplemented with 1% Trition–X100 and protease inhibitors. Approximately 0.5mg of protein extract is incubated with 100 μM HSF1A–Biotin for 4 h at 4°C and HSF1A–Biotin associated proteins captured by with NeutrAvidin Agarose Resin. After washing in biotin binding buffer proteins are eluted using 50 μL biotin elution buffer (100 mM Tris,150 mM NaCl, 0.1 mM EDTA, 2 mM D–biotin), resolved on a 4–20% SDS–PAGE, and immunoblotted. For purified TRiC and Hsp70analyses, 5 nM protein is incubated in biotin–binding buffer+0.5% Triton X–100 with 100 μM biotin or 100 μM HSF1A–Biotin for 4 h at 4°C and captured with NeutrAvidin Resin. For NiNTA purified yeast Tcp1, different concentrations of Tcp1 0.5 μM, 1 mM, 2 mM, 3 mM and 4 mM in 25 mM Hepes pH 7.5, 150 mM NaCl are incubated with 0.5 μM Biotin or HSF1A–Biotin for 4 h at 4°C and captured with NeutrAvidin Resin [1].Cell Assay:[2]PC12 cells seeded into a 96–well plate (5×104 cells/well) are treated with increasing concentrations of HSF1A (2, 4, 8 andProduct Name:HSF1A Cat. No.:HY-103000CAS No.:1196723-93-9Molecular Formula:C21H19N3O2S2Molecular Weight:409.52Target:HSP Pathway:Cell Cycle/DNA Damage; Metabolic Enzyme/Protease Solubility:DMSO: ≥ 150 mg/mL12 μM) for 15 h, at which time httQ74–GFP expression is stimulated by incubation in the presence of 1 μg/mL Doxycycline for 5 d. Cell viability is assessed via the XTT viability assay[2].Animal Administration:[3]Rat[3]Ten–week–old Wistar Kyoto rats (WKY) are used. The rats are housed at a constant temperature (22°C) on a 12–h light/dark cycle with food and tap water. The animals are arranged into three groups: WKY rats (the control group), DOX rats and DOX rats treated with HSF1A. Each group contain five animals. The DOX group is injected with DOX (5 mg/kg) for 6 consecutive weeks intraperitoneal injection to achieve a cumulative dose of 30 mg/kg, which has been well documented to achieve cardiotoxicity. The small molecular HSF1 activator HSF1A (100 mg/kg/day) is injected intraperitoneally.References:[1]. Neef DW, et al.

ACCUSPIN系统-Histopaque 1077产品说明书

ACCUSPIN系统-Histopaque 1077产品说明书

Technical BulletinACCUSPIN™ System – Histopaque ® 1077Catalog Numbers A6929, A7054, and A0561Product DescriptionACCUSPIN System-Histopaque -1077products are intended for use in the isolation of lymphocytes and other mononuclear cells. The separation medium, Histopaque-1077, is a sterile-filtered, endotoxin tested solution of polysucrose and sodium diatrizoate, adjusted to a density of 1.077 g/mL. The ACCUSPIN tube is specially designed with two chambers separated by a porous high density polyethylene barrier (frit).Separation of lymphocytes and other mononuclear cells from whole blood and bone marrow using density gradientseparation media is based on a published method.1 Histopaque-1077 is suitable for human lymphocyte antigen (HLA) typing 2 and as the initial isolation step prior toenumeration of T, B, and ‘null’ lymphocytes.3 It may also be employed in the preparation of pure lymphocyte suspensions for cell culture and cytotoxicity assays.4ACCUSPIN System-Histopaque-1077 products consist of radiation sterilized polypropylene tubes fitted with a highdensity polyethylene frit and aseptically filled with Histopaque-1077.Histopaque-1077 is a sterile-filtered solution of polysucrose, 57 g/L, and sodium diatrizoate, 90 g/L.Density: 1.076–1.078 g/mL Endotoxin: 0.3 EU/mL pH: 8.8–9.0ACCUSPIN System-Histopaque-1077Catalog No. A692940 × 3 mLEach tube contains 3 mL ofHistopaque 1077-1 and will separate 3-6 mL of anticoagulated blood Catalog No. A7054 12 × 15 mLCatalog No. A0561100 × 15 mLEach tube contains 15 mL ofHistopaque 1077-1 and will separate 15-30 mL of anticoagulated bloodReagents and Equipment Required but Not ProvidedCentrifuge (swinging bucket rotor)capable of generating 100 to 1,000 g Centrifuge tubes for washing mononuclear cellsIsotonic phosphate buffered saline solution or appropriate cell culture mediumPrecautions and DisclaimerFor R&D use only. Not for drug, household, or other uses. Please consult the Safety Data Sheet for information regarding hazards and safe handling practices.Preparation InstructionsSpecimen Collection - Collect blood in preservative-free anticoagulant (EDTA or heparin) or use defibrinated blood. For best results, blood should be processed within 2 hours.On occasion, it may be necessary to dilute the blood sample 3 to 5-fold, depending on absolute cell numbers. A similar volume of prediluted blood may be used or the blood sample may be diluted directly in upper chamber of the ACCUSPIN tube (seeProcedure, step 3). This is appropriate for specimens with hematocrits above normal.Storage/StabilityStore the products at 2–8 C.Histopaque-1077 has an expiration period of 3 years. Reagent label bears expiration date.ProcedureAnticoagulated blood can be added to the top chamber of the tube without risk of mixing with the Histopaque-1077 in the lowerchamber under the frit. On centrifugation the whole blood migrates through the frit to contact with the Histopaque-1077. The elements of greater density displace a volume of Histopaque-1077 above the frit giving a clear separation of the bloodcomponents. The erythrocytes aggregate and the granulocytes become slightly hypertonic, increasing their sedimentation rate, resulting in pelleting at the bottom of the ACCUSPIN Tube. Lymphocytes and other mononuclear cells, e.g., monocytes, remain at the plasma/Histopaque-1077 interface. This dense band of mononuclear cells may be collected by pouring off the contents of the upper chamber or by means of a pipette. Erythrocyte contamination is avoided due to the barrier between the chambers.Most extraneous platelets are removed by low speed centrifugation during the washing steps.1. Bring desired number of tubes to roomtemperature. If Histopaque-1077 isabove the frit prior to use, centrifuge at 1,000 g for 30 seconds at room temperature.Note: Failure to bring ACCUSPIN System-Histopaque-1077 to room temperature may cause limited recovery of mononuclear cells. 2. Label tube(s).3. Freely pour the blood sample into theupper chamber of each ACCUSPIN System-Histopaque-1077 tube.a. Use 3–6 mL of whole blood withACCUSPIN System-Histopaque-1077 tubes, Catalog No. A6929. b. Use 15–30 mL of whole blood withACCUSPIN System-Histopaque-1077 tubes, Catalog Nos. A7054 or A0561. Note: Use of volumes of prediluted or whole blood other than those recommended may result in decreased recovery.4. Centrifuge at 1,000 g for 10 minutes atroom temperature or centrifuge at 800 g for 15 minutes at roomtemperature. Centrifugation at lower temperatures, such as 4 C, may result in cell clumping and poor recovery.Note: If platelet contamination is a concern, add the mononuclear cells to a 4-20% sucrose gradient that has been layered over Histopaque-1077.Centrifuge at 1,000 × g for 10 minutes at room temperature. The platelets will pellet at the bottom, while themononuclear cells will migrate to the Histopaque-1077 layer.5. After centrifugation, carefully aspiratethe plasma layer with a Pasteur pipette to within 0.5 cm of the opaque interface containing mononuclear cells. Properly dispose of the plasma layer.Note: Failure to remove the excesssupernatant may result in contamination of the mononuclear band with plasma proteins.6. Carefully transfer the opaque interfacewith a Pasteur pipette into a clean conical centrifuge tube.Note: Removal of Histopaque-1077 with the mononuclear band increasesgranulocyte contamination from residual granulocytes, which may remain at the mononuclear interface.7. Wash the cells by adding 10 mL ofisotonic phosphate buffered saline solution or appropriate cell culture medium and mix by gently drawing in and out of a Pasteur pipette. 8. Centrifuge at 250 g for 10 minutes. 9. Aspirate the supernatant and discard. 10. Resuspend cell pellet with 5 mL ofisotonic phosphate buffered saline solution or appropriate cell culture medium and mix by gently drawing in and out of a Pasteur pipette.11. Centrifuge at 250 g for 10 minutes. 12. Repeat steps 9, 10, and 11, discardsupernatant and resuspend cell pellet in 0.5 mL of isotonic phosphate buffered saline solution or appropriate cell culture medium. Erythrocytes and granulocytes should pellet to the bottom of the ACCUSPIN tube. Mononuclear cells should band at the interface between the Histopaque-1077 and the plasma.

CFDA SE (细胞增殖示踪荧光探针) 说明书

CFDA SE (细胞增殖示踪荧光探针) 说明书

CFDA SE (细胞增殖示踪荧光探针) 产品编号产品名称包装C1031 CFDA SE (细胞增殖示踪荧光探针) 5mg产品简介:CFDA SE 的全称为Carboxyfluorescein diacetate, succinimidyl ester ,是一种近年来被广泛应用的细胞增殖检测用荧光探针,也可以用于细胞的荧光示踪。

基于CFDA SE 荧光标记的细胞增殖检测和[3H]-thymidine 掺入、BrdU 标记获得的检测结果完全一致,但同时可以提供更多的细胞增殖信息。

使用CFDA SE 检测可以提供整个细胞群中有多少比例的细胞分裂了1次、2次或更多次数,同时如果和其它荧光探针联用,可以获取不同分裂次数细胞的其它相关信息。

CFDA-SE 的分子式为C 29H 19NO 11,分子量为557.47,CAS number 为150347-59-4。

CFDA SE 可以通透细胞膜,进入细胞后可以被细胞内的酯酶(esterase)催化分解成CFSE ,CFSE 可以偶发性地(spontaneously)并不可逆地和细胞内蛋白的Lysine 残基或其它氨基发生结合反应,并标记这些蛋白。

在加入荧光探针CFDA SE 后大约24小时,即可充分标记细胞。

被CFDA SE 标记的非分裂细胞的荧光非常稳定,稳定标记的时间可达数个月。

CFDA SE 标记细胞的荧光非常均一,比以前使用的其它细胞示踪荧光探针例如PKH26的荧光更加均一,并且分裂后的子代细胞的荧光分配也更均匀。

由于CFDA SE 标记细胞的荧光非常均匀和稳定,每分裂一次子代细胞的荧光会减弱一半,这样通过流式细胞仪检测就可以检测出没有分裂的细胞,分裂一次的细胞(1/2的荧光强度),分离两次的细胞(1/4的荧光强度),分裂三次的细胞(1/8的荧光强度)以及类似的其它分裂次数的细胞。

采用CFDA SE 通过流式细胞仪检测获得的检测结果参考右图。

每一个峰代表一种分裂次数的细胞,从右至左的峰通常依次为分裂0次、1次、2次、3次等次数的细胞。

Enzyme/Coenzyme/ 5 x 100 ml α-oxoglutarate GTIN: 05055273200454UV METHODThis is an optimised standard method according to the concentrations recommended by the IFCC.CLINICAL SIGNIFICANCE (1,2,3,4)The aminotransferases are a group of enzymes that catalyse the inter conversions of amino acids and α-oxoacids by transfer of amino groups. AST (aspartate aminotransferase or glutamate oxaloacetatetransaminase) has been found in the cytoplasm and the mitochondria of cells that have been studied. In cases of mild tissue damage, e.g. liver, the predominant form of serum AST is that from the cytoplasm, with a smaller amount coming from the mitochondria. Severe tissue damage will result in more mitochondrial enzyme being released. Elevated levels of AST can signal myocardial infarction, hepatic disease, muscular dystrophy and organ damage.Although heart muscle is found to have the most activity of the enzyme, significant activity has also been seen in the brain, liver, gastric mucosa, adipose tissue and kidneys of humans.The IFCC has now recommended (1980) standardised procedures for AST determinations including:-1. optimization of substrate concentrations.2. Employment of Tris buffers (instead of phosphate, which has beenshown to inhibit recombination of the apoenzyme with pyridoxal phosphate).3. Pre-incubation of combined buffer and serum to allow sidereactions with NADH to occur. 4. Substrate start (α-oxoglutarate)5. Optional pyridoxal phosphate activation.This is an optimised standard method according to the recommendations of the IFCC.PRINCIPLEα-oxoglutarate reacts with L-aspartate in the presence of AST to form L-glutamate plus oxaloacetate. The indicator reaction utilises the oxaloacetate for a kinetic determination of NADH consumption. AST -oxoglutarate + L-aspartate L-glutamate + oxaloacetate MDH oxaloacetate + NADH + H + L-malate + NAD +SPECIMEN COLLECTION AND PREPARATION (5) Serum:- Use serum free from haemolysis.Plasma:- EDTA or heparin can be used as the anticoagulant.Plasma should be separated from cells within one hour after collection.Specimens should be refrigerated if not used immediately:-Specimens stored longer than 3 days should be frozen at -20︒C.REAGENT COMPOSITIONContents Concentrations in the TestR1a.
