Terminator 5′-Phosphate-Dependent Exonuclease 产品说明

ManualTerminator 5′-Phosphate-Dependent ExonucleaseF or Research Use Only. Not for use in diagnostic procedures.Contents1. Introduction (3)2. Product designations and kit components (3)3. Product specifications (3)4. General considerations (3)5. Standard procedure (5)6. Alternative procedure (5)7. Further support (7)1. IntroductionTerminator 5′-Phosphate-Dependent Exonuclease is a processive 5′→3′ exonuclease that digests RNA having a 5′ monophosphate. It does not digest RNA having a 5′-triphosphate, 5′-cap or 5′-hydroxyl group. These enzymatic properties make Terminator Exonuclease ideal for producing mRNA-enriched samples from both eukaryotic and prokaryotic total RNA preparations by selectively digesting the ribosomal RNA (rRNA).Terminator Exonuclease can be used to isolate eukaryotic mRNA substantially free of 18S and 28S rRNA without using an oligo(dT) matrix. Further, Terminator Exonuclease provides a simple andeffective method for purifying unprocessed, primary bacterial transcripts by removing large rRNA and other processed transcripts.Terminator Exonuclease will also digest single-stranded DNA (ssDNA) having a 5′-phosphate group. It does not digest ssDNA or dsDNA having a 5′-triphosphate or a 5′-hydroxyl group. Terminator Exonuclease is not inhibited by RNase inhibitors such as RNasin (Promega Corporation), Prime RNase Inhibitor (Eppendorf AG) or RiboGuard™ RNase Inhibitor.Terminator 5′-Phosphate-Dependent Exonuclease is available in a 40 unit size at a concentration of 1 U/µL. Two different Terminator 10X Reaction Buffers are also provided with the enzyme, each optimised for different applications.2. Product designations and kit componentsProductKit size Reagent description Catalogue number Part number Volume 3. Product specificationsStorage: Store only at -20 °C in a freezer without a defrost cycle.Storage buffer: Terminator Exonuclease is supplied in a 50% glycerol solution containing 50 mM Tris-HCl (pH 7.5), 0.1 M NaCl, 0.1 mM EDTA, 1 mM dithiothreitol and 0.1% Triton X-100.Unit definition: One unit digests 1 μg of rRNA substrate into acid-soluble nucleotides in 60 minutes at 30 °C under standard assay conditions.Quality control: Terminator Exonuclease is function-tested in a 50 µL reaction containing 50 mM Tris-HCl (pH 8.0), 2 mM MgCl 2, 100 mM NaCl, 20 μg rRNA and varying amounts of enzyme.Contaminating activity assays: Terminator Exonuclease is free of detectable contaminating endonuclease and non-5′-phosphate-dependent nuclease activities.4. General considerationsIntegrity of the RNA sample: The success of a Terminator Exonuclease reaction is strongly influenced by the quality of the total RNA sample used in the reaction. Therefore, it is important to confirm the purity and integrity of the RNA sample prior to beginning the reaction.RNA sample: The RNA sample to be treated with Terminator Exonuclease should be dissolved in RNase-free water prior to treatment.IMPORTANT: Do not dissolve the RNA sample in TE buffer (10 mM Tris-HCl [pH 7.5], 1 mM EDTA) or any other EDTA-containing buffer. EDTA concentrations as low as 1 mM will inhibit Terminator Exonuclease activity.Maintaining an RNase-free environment: Ribonuclease contamination is a significant concern for those working with RNA. The ubiquitous RNase A is a highly stable and active ribonuclease that can contaminate any lab environment and is present on human skin.Creating an RNase-free work environment and maintaining RNase-free solutions is critical for performing successful reactions. Therefore, we strongly recommend that the user:1) Autoclave all tubes and pipette tips that will be used in the reactions.2) Always wear gloves when handling samples containing RNA. Change gloves frequently especiallyafter touching potential sources of RNase contamination such as door knobs, pens, pencils and human skin.3) Always wear gloves when handling reaction components. Do not pick up the enzyme or buffer withan ungloved hand.4) Keep all components tightly sealed when not in use. Keep all tubes containing RNA tightly sealedduring the incubation steps.Buffer/protocol choice: Terminator 5′-Phosphate-Dependent Exonuclease is a processive 5′→3′ exonuclease that digests RNA that has a 5′ monophosphate. It does not digest RNA that has a5′-triphosphate, 5′-cap or 5′-hydroxyl group. However, on rare occasions, we have observed a secondary, non-5′-monophosphate-specific activity on 5′-triphosphate and 5′-hydroxyl RNAs. Because of this activity, two different 10X Reaction Buffers are provided with this kit. The Terminator 10X Reaction Buffer A and its affiliated protocol constitute the standard buffer and protocol. They have been optimised for maximum 5′-monophosphate RNA digestion (e.g., rRNA digestion). The Terminator 10X Reaction Buffer B and its affiliated protocol are provided as an alternate method that should only be used in the rare event that a specific RNA of interest is being degraded by a secondary non-5′-monophosphate-specific activity. Note, however, that less rRNA will be degraded with this buffer and protocol.NOTE: For best digestion, total input RNA must be of high quality (RNA Integrity Number of at least 8 when evaluated on an Agilent Bioanalyzer Model 2100).NOTE: Using the two different buffers in a 50:50 ratio will not produce a reaction condition with the benefits of each individual buffer and protocol.5. Standard procedureIMPORTANT: Two different reaction buffers and protocols are included with Terminator Exonuclease. Be sure to read Buffer/Protocol Choice (section above) to determine which protocol is appropriate for your intended use. Use one or the other. Do not mix buffers.This protocol uses the Terminator 10X Reaction Buffer A and has been optimised for maximum5′-monophosphate rRNA digestion (e.g., rRNA digestion). Buffer B may be used for very low-mass RNA samples.The RNA sample to be treated should be dissolved in RNase-free water. Do not dissolve the RNA sample in TE buffer.1. Gently mix and briefly centrifuge the Terminator 10X Reaction Buffer A prior to use.2. In a sterile (RNase-free) 0.2 mL or 0.5 mL tube, combine the following reaction components on ice:x μL RNase-free water2 µL Terminator 10X Reaction Buffer A0.5 µL RiboGuard RNase Inhibitory µL Total RNA Sample (200 ng-10 μg)1 μL Terminator Exonuclease (1 unit)20 μL Total reaction volume3. Incubate the reaction at 30 °C for 60 minutes in a thermocycler (with heated lid) or Water bath.4. Terminate the reaction by one of the two methods described in Section 6, Step 4.6. Alternative procedureIMPORTANT: Two different reaction buffers and protocols are included with Terminator Exonuclease. Be sure to read Buffer/Protocol Choice (section above) to determine which protocol is appropriate for your intended use.This protocol uses the Terminator 10X Reaction Buffer B and should only be used in the rare event that a specific RNA of interest is being degraded by a secondary non-5′-monophosphate-specific activity of the enzyme.NOTE: Less rRNA will be degraded with this buffer and protocol.The RNA sample to be treated should be dissolved in RNase-free Water. Do not dissolve the RNA sample in TE buffer.1. Gently mix and briefly centrifuge the Terminator 10X Reaction Buffer B prior to use.2. In a sterile (RNase-free) 0.2-mL or 0.5-mL tube, combine the following reaction components on ice:x μL RNase-free water2 µL Terminator 10X Reaction Buffer B0.5 µL RiboGuard RNase Inhibitory Total RNA Sample (1-2.5 μg)1 μL Terminator Exonuclease (1 unit)20 μL Total reaction volume3. Incubate the reaction at 42 °C for 30 minutes in a thermocycler (With heated lid) or Water bath.4. Terminate the reaction by one of the two methods described below:4a. Terminate the reaction by adding 1 µL of 100 mM EDTA (pH 8.0).Place the reaction on ice. Note that the enriched mRNA sample will now contain 5 mM EDTA (as well as tRNA, nucleotides and other small RNAs). It may be used directly for applications in which the EDTA will not be inhibitory. However, the high concentration of EDTA may interfere with some subsequent uses of the mRNA, such as RT-PCR. Therefore, it may be necessary to remove the excess EDTA by LiCl precipitation (see beloW), ethanol precipitation or use of anRNA purification column.4b. Terminate the reaction by phenol extraction and ethanol precipitation.1. Add RNase-free water to the reaction to a total volume of 200 µL. Extract once withbuffer-saturated phenol.2. Transfer the aqueous phase to a new RNase-free tube.3. Add 0.1 volume of 3 M sodium acetate and 2.5 volumes of ethanol to the aqueous phaseand mix thoroughly.4. Incubate on ice or at -20 °C for 30 minutes.5. Pellet the RNA by centrifugation in a microcentrifuge for 30 minutes at full speed at 4 °C.6. Carefully remove and discard the supernatant. Do not disturb the RNA pellet which containsthe mRNA.7. Wash the RNA pellet with 70% ethanol to remove residual salt. Resuspend the RNA pellet inRNase-free water or TE buffer.5. (Optional) Purify the enriched mRNA. If desired, the enriched mRNA can be purified from excessEDTA, tRNA, 5S rRNA and other small RNA species, by LiCl precipitation or by using a commercial RNA purification column.Lithium chloride precipitation should be performed only if the original reaction contains >2 μg of total RNA. If the amount of total RNA in the reaction was less than 2 μg, purify the mRNA by phenol extraction and ethanol precipitation as described above or using a commercial RNA purification column.Lithium chloride selectively precipitates large RNA such as mRNA, while small RNA such as tRNA1. Add 1 volume of 5 M LiCl solution to the sample and mix well.2. Incubate on ice or at -20 °C for 30 minutes.3. Pellet the RNA in a microcentrifuge for 30 minutes at full speed at 4 °C.4. Carefully remove and discard the supernatant Which contains the tRNA, other small RNAs andnucleotides. Do not disturb the RNA pellet which contains the mRNA.5. Wash the RNA pellet with 70% ethanol to remove residual salt.6. Resuspend the RNA pellet in RNase-free Water or TE buffer.7. (Optional) Analyse the effectiveness of the Terminator reaction by denaturing agarose gelelectrophoresis or using an Agilent 2100 Bioanalyzer. When using either method, it is important to run an untreated RNA sample (~250 ng of total RNA) alongside the treated sample. Theabsence of 18S and 28S rRNA in the post-treatment sample indicates a successful reaction.7.

ICHQ9 and the newAnnex 1 written by EMA in cooperation with the US-FDA,WHO, and PICs) also applies to filter integrity testing,as a fundamental element of sterility assurance.The Sartocheck® 5 Plus Filter Tester uses program-specificparameters allowing the automatic identification oftesting anomalies before or during the test. This preventstime-consuming, costly variations, potential drug recalls,and 483 warning letters.Experience the Comfort of Intuitive UsabilityAn optimal user experience speeds up process workflowsdue to intuitive guidance and ease of use. The high-qualitytouchscreen of the Sartocheck® 5 Plus Filter Testerprovides a unique viewing angle, an intuitive user interface,a logical menu structure, and simple data entry options.This allows straightforward programming of tests andQRM enhancement features, as well as error-free operationin GMP production environments.Reach the Ultimate Level of Data IntegrityFilter integrity test values are part of the batch protocoland are used to justify the drug release. Long-term reliabledata is crucial to avoid quality deviations and potential 483warning letters.The integrity and security of filter integrity test data mustnot be seen only as an IT problem, but also as a potentialglobal business risk. Low standards of data integrity andsecurity may not only jeopardize the activities of the drugmanufacturing company, but more critically, endanger thehealth of patients.Discover the Simplicity of HSEIntegrity testing often involves the use of chemicals andhazardous materials, e.g., alcohol. The Sartocheck® 5 Plusis certified for use in explosion-hazardous areas (ATEX)and is compatible with all current cleaning agentsand VHP. This ensures maximum safety for operatorsand manufacturing facilities.Pneumatics Max. inlet pressure 8,000 mbar | 116 psiOverpressure protection Max. inlet pressure + 4,000 mbar Min. inlet pressure 4,000 mbar | 58 psiInternal reference volume1,023 mL conforming to Pressure Equipment Directive 2014/68/EU max.

The test result rounding is done according to the tie-breaking rule called “round half to even”. This is the default rounding mode used in IEEE 754 computing functions and operators.Storage and Transportation ConditionsFrom -10 °C to +60 °C (14 – 140 °F) at 90% RH noncondensing humidity.The

霉酚酸在肾移植患者中有限采样法监测方案的探讨

霉酚酸在肾移植患者中有限采样法监测方案的探讨*王娟1,2,王丽彬1,郭苗1**,魏继福1**1南京医科大学第一附属医院药学部,南京210029;2南京鼓楼医院药学部,南京210008;霉酚酸(mycophenolic acid ,MPA )因肾毒性低的优点,广泛应用于肾移植术后的免疫抑制治疗[1]。
其通过选择性可逆地抑制鸟嘌呤核苷酸从头合成途径的关键酶次黄苷酸脱氢酶(inosine monophos ⁃phate dehydrogenase ,IMPDH )的活性,抑制T 、B 淋巴细胞增殖,从而发挥免疫抑制作用[2]。
多项研究表明,肾移植患者按固定剂量给药时,MPA 的药代动力学和药效学具有明显的个体间和个体内差异,其受诸多因素的影响,如性别、体重、种族、白蛋白水平、肝肾功能、移植后时间、基因多态性等[3]。
据文献报道,MPA 的血浆浓度-时间曲线下面积(area un ⁃der plasma concentration-time curve ,AUC )与其临床抗排斥效果和不良反应的发生具有明显的相关性,然而谷浓度与AUC 相关性较差[4]。
本文主要确定了吗替麦考酚酯和霉酚酸钠肠溶片的AUC 血药浓度监测简化方案,为实现MPA 在肾移植患者中的个体化应用提供参考。
1对象与方法1.1研究对象临床应用的MPA 类药物主要有吗替麦考酚酯(mycophenolate mofetil ,MMF )和霉酚酸钠肠溶片(enteric-coated mycophenolate sodium ,EC-MPS )。
本研究共纳入76例成人肾移植患者,考察MPA 的药代动力学特征。
分两组:MMF 组33例(男性21例、女性12例),年龄19~57岁;EC-MPS 组43例(男性32例、女性11例),年龄24~61岁。
所有患者均在南京医科大学第一附属医院手术及术后随访,均采用MPA 、他克莫司(Tac )、激素三联免疫抑制方案治疗。
