Description

The ThermoScript ? RT-PCR System is designed for the sensitive and reproducible detection and analysis of RNA molecules in a two-step process. ThermoScript ? RT, an avian reverse transcriptase with reduced RNase H activity, is engineered to have higher thermal stability,

produce higher yields of cDNA, and produce more full-length cDNA transcripts than AMV RT. cDNA synthesis is performed in the first step using either total RNA or poly(A)+-selected RNA primed with oligo(dT), random primers or a gene-specific primer, at 50-65°C. In the second step, PCR is performed in a separate tube using primers specific for the gene of interest. RNA targets from 100 bp to >12 kb can be detected with this system, using 10 pg to 5 Yg of total RNA. PCR is carried out with Platinum ? Taq DNA Polymerase or Platinum ? Taq DNA Polymerase High Fidelity. Platinum ? Taq DNA Polymerase High Fidelity is suitable for templates from 100 bp to >12 kb. Platinum ? Taq DNA polymerase (1) provides automatic hot-start conditions for increased specificity up to 3 kb.

Reagents are provided for 25 or 100 cDNA synthesis reactions of 20 μl each and 25 or 100 amplification reactions of 50 μl each.

Page 2 of 4 Important Parameters to Consider

RNA

?High quality intact RNA is essential for successful full-length cDNA synthesis and successful long RT-

PCR.

?RNA should be devoid of any RNase contamination and aseptic conditions should be maintained. ?Recommended methods of total RNA isolation include the Micro-to-Midi Total RNA Purification

System (Catalog no. 12183-018) and TRIzol? Reagent

(Catalog no. 15596-026) (2, 3). Oligo(dT)-selection for

poly(A)+ RNA is typically not necessary, although

incorporating this step may improve the yield of

specific cDNAs.

cDNA Synthesis Primers

?Oligo(dT)20 (50 pmoles/reaction) is recommended for priming polyadenylated RNA. Use of Oligo(dT)20

allows the detection of multiple transcripts from a

single first-strand reaction.

?Random hexamers (50-250 ng/reaction) are efficient primers for the detection of multiple short RT-PCR

targets. Use of more than 50-100 ng primer/Yg of

RNA can increase the yield of short products but may inhibit detection of long targets (>3kb) or rare

transcripts. If random hexamers are used, the first-

strand reaction must be incubated at 25°C for 10 min

to extend the primers prior to increasing the reaction

temperature for synthesis.

?Gene-specific primers (GSP) should be used at 10 to

20 pmol/reaction. Specificity of priming may be

improved by optimizing annealing/reaction

temperature.

?Treatment of cDNA with RNase H to remove the complementary RNA prior to PCR is optional. RNase

H digestion will improve the RT-PCR signal of many

targets and is required for the efficient and consistent

amplification of long RT-PCR templates.

cDNA Synthesis Reaction

?Denaturation of the RNA template and primer by incubating at 65°C for 5 min is optional. Most targets

can be reverse transcribed efficiently without this step.

However, heating the RNA in the absence of reaction

buffer and enzyme prior to cDNA synthesis can

remove secondary structure that may impede full-

length cDNA synthesis.

?ThermoScript? RT can be used at 50-65°C. We recommend incubation at 50-55°C for most RT-PCR

targets. However, incubation at 50-60°C for oligo(dT)

and 50-65°C for gene-specific primers can be

employed to reduce secondary structure or to improve specificity.

?Most targets can be amplified after only a 30-min incubation for the first-strand reaction. Rare RNAs,

long transcripts, or targets at the 5′ end of long

transcripts benefit from longer incubation times (50-60 min).PCR Primers

? A final primer concentration of 0.2 - 0.4 μM for each primer is generally optimal; however, a primer

titration is recommended for best results.

?Design primers that anneal to sequence in exons on both sides of an intron or exon/exon boundary of the mRNA to allow differentiation between amplification of cDNA and potential contaminating genomic DNA. ?Primers should not be self-complementary or complementary to each other at the 3′ ends.

PCR Reactions

?Most targets will be efficiently amplified using 2 Yl or less of the cDNA synthesis reaction.

?The optimum magnesium concentration varies from

1.5 to 3 mM. Generally, 1.82 mM magnesium chloride

for Platinum? Taq DNA polymerase and 2.32 mM

magnesium sulfate for Platinum? Taq DNA

Polymerase High Fidelity is effective for most primer sets. However, titration of the magnesium

concentration is recommended for the best result.

Each Yl of the cDNA synthesis reaction adds 0.16 mM to the final magnesium concentration in a 50-μl PCR

reaction.

?Assemble the PCR reactions on ice, transfer them to a pre-heated thermal cycler (85-95°C) and immediately start the PCR amplification program.

?The annealing temperature should be 10°C below the melting temperature of the primers used.

?The optimum extension temperature for Platinum?Taq DNA Polymerase High Fidelity is 68°C. The

extension time varies with the size of the amplicon

(approximately 1 min per 1 kb of amplicon).

一步法RT-PCR 检测试剂盒 (一步法RT-PCR 扩增试剂盒) (目录号HS0612-2) 产品包装 保存条件 -20℃ 产品简介 本试剂盒是专为一步法RT-PCR 实验研制,逆转录和PCR 在同一反应体系中进行,反应过程中无需添加试剂,无需打开管盖,在避免污染的同时提高了检测灵敏度和实验效率。本试剂盒包括全新高效逆转录酶、快速热启动DNA 聚合酶,同时包含适用于逆转录和PCR 扩增的反应缓冲液和实验中所必需的反应组分。经过重组表达的SuperRT 逆转录酶RNase H 活性缺失,减少了逆转录反应中RNA 的降解,更容易获得全长的cDNA 。该逆转酶逆转录效率高,可对少量 RNA 模板进行良好的逆转录反应。SuperRT 逆转录酶与RNA 亲合性高,能通读GC 含量高,二级结构复杂的RNA 模板,获得高产量的cDNA 。PCR 反应使用的DNA 聚合酶具有扩增效率高、延伸速度快的优良性能。独特的缓冲体系使逆转录酶和聚合酶同时发挥最大功效。使用该试剂盒能够方便快捷的在同一个反应管内完成逆转录和PCR 扩增反应。使用本试剂盒扩增得到的目的产物3′端附有一个″A ″碱基,可直接用于T/A 克隆。 北京厚生博泰科技有限公司 Beijing Hooseen Biotech Co., Ltd.

产品特点 1. 效率高,可以高效转录GC含量高,二级结构复杂的RNA模板。 2. 耐热性及稳定性强。 3. 操作简单迅速,最大限度的避免污染。 4. 独特的缓冲体系使逆转录酶和聚合酶同时发挥最大功效。 使用方法

1)一般PCR实验中退火温度比扩增引物的熔解温度Tm低5℃,退火时间一般为20 ~ 30秒,无法得到理想的扩增效率时,适当降低退火温度;发生非特异性反应时,提高退火温度,由此优化反应条件。 2)延伸时间根据所扩增的片段大小设定,本产品中所包含的DNA Polymerase的扩增效率为1 kb/30s。 3)可根据扩增产物的下游应用设定循环数。循环次数太少,扩增量不足;循环次数多,错配机率会增加,非特异性背景严重。所以,在保证产物得率的前提下,应尽量减少循环次数。 5. 反应结束后取5 ul反应产物,加入适量上样缓冲液后进行电泳检测结果。

Taq DNA polymerase) 11146-040 (w/ Platinum ? Taq DNA polymerase High Fidelity) Store at -20°C (stability can be extended by storing at -70°C) Description The ThermoScript ? RT-PCR System is designed for the sensitive and reproducible detection and analysis of RNA molecules in a two-step process. ThermoScript ? RT, an avian reverse transcriptase with reduced RNase H activity, is engineered to have higher thermal stability, produce higher yields of cDNA, and produce more full-length cDNA transcripts than AMV RT. cDNA synthesis is performed in the first step using either total RNA or poly(A)+-selected RNA primed with oligo(dT), random primers or a gene-specific primer, at 50-65°C. In the second step, PCR is performed in a separate tube using primers specific for the gene of interest. RNA targets from 100 bp to >12 kb can be detected with this system, using 10 pg to 5 Yg of total RNA. PCR is carried out with Platinum ? Taq DNA Polymerase or Platinum ? Taq DNA Polymerase High Fidelity. Platinum ? Taq DNA Polymerase High Fidelity is suitable for templates from 100 bp to >12 kb. Platinum ? Taq DNA polymerase (1) provides automatic hot-start conditions for increased specificity up to 3 kb.

RNA样品要避免基因组DNA污染。 3. 避免多次反复冻融RNA,使RNA保持在冰浴中处融化状态。 4. 试剂盒的各组成成分应在-20℃保存。 5. cDNA产物应置于-20℃保存。 操作步骤: 1. 在冰浴的无核酸酶的离心管中加入如下反应混合物: 1-5 μg总RNA或50-500 ng mRNA; 2 μl oligo (dT)15或2 μl Random或2 pmol基因特异引物; 2 μl Super Pure dNTPs mM each); 补RNase-Free ddH2O定容至μl。 2. 70℃加热5min后迅速在冰上冷却 2 min。简短离心收集反应液后加入以下各组分: 4 μl 5×First-Strand Buffer (含有DTT);μl RNasin。 3. 加1 μl(200U)TIANScript M-MLV,轻轻用移液器混匀。如果用随机引物,请将离心管置25℃温浴10 min。 4. 42℃温浴50 min。 5. 95℃加热5 min终止反应,置冰上进行后续实验或冰冻保存。 如果需要RNase H处理,进行步骤6。否则,进行步骤7。 6. 加RNase H 1 μl (2 U),37℃温浴20 min以降解RNA。然后95℃加热5 min 使酶失活。 7. 用RNase-Free ddH2O将反应体系稀释到50 μl,取2-5 μl进行PCR扩增反应。 PCR反应: 应吸取10%的第一链反应液(2 μl)进行PCR反应;即使加入更多量的第一链反应液也不能增加其扩增的产物量,反而可能会抑制正常的PCR反应。 1. 请将以下成分加入到一PCR管中并使其终反应体积为50 μl:

逆转录-聚合酶链(RT-PCR)实验的具体步骤及方法

逆转录-聚合酶链(RT-PCR)实验的具体步骤及方法 提取组织或细胞中的总RNA,以其中的mRNA作为模板,采用Oligo(dT)或随机引物利用逆转录酶反转录成cDNA,再以cDNA为模板进行PCR扩增,从而获得目的基因或检测基因表达。 一、总RNA的提取 见总RNA的提取相关内容。 二、cDNA第一链的合成 目前试剂公司有多种cDNA第一链试剂盒出售,其原理基本相同,但操作步骤不一。现以GIBICOL公司提供的SuperScriptTM Preamplification System for First Strand cDNA Synthesis 试剂盒为例。 1.在0.5 ml微量离心管中,加入总RNA 1-5 ug,补充适量的DEPC H2O使总体积达11 ul。在管中加10 uM Oligo(dT)12-18 1 ul,轻轻混匀、离心; 2.70℃加热10min,立即将微量离心管插入冰浴中至少1min; 3.取0.5 ml PCR管,依次加入下列试剂:第一链cDNA 2 ul;上游引物(10 pM)2 ul;下游引物(10 pM)2 ul;dNTP(2mM) 4 ul;10x PCR buffer 5 ul;Taq 酶(2 u/ul)1 ul。轻轻混匀,离心。42℃孵育2-5 min;

4.加入SuperscriptⅡ1 ul ,在42℃水浴中孵育50 min; 5.于70℃加热15 min以终止反应; 6.将管插入冰中,加入RNase H 1 μl ,37℃孵育20 min,降解残留的RNA。-20℃保存备用。 三、PCR 1.取0.5 ml PCR管,依次加入下列试剂:第一链cDNA 2 ul;上游引物(10 pM)2 ul;下游引物(10 pM)2 ul;dNTP(2 mM) 4 ul;10x PCR buffer 5 ul;Taq 酶(2 u/ul)1 ul; 2.加入适量的ddH2O,使总体积达50 ul。轻轻混匀,离心; 3.设定PCR程序。在适当的温度参数下扩增28-32个循环。为了保证实验结果的可靠与准确,可在PCR扩增目的基因时,加入一对内参(如G3PD)的特异性引物,同时扩增内参DNA,作为对照; 4.电泳鉴定:行琼脂糖凝胶电泳,紫外灯下观察结果;
