■ 制品内容 (Code No.: 2641A)
Reverse Transcriptase M-MLV (RNase H-)(200 U/μl) 10,000 U
5X Reverse Transcriptase M-MLV Buffer 1 ml
 
■ 制品说明
本制品是通过基因重组技术克隆表达的缺失突变型RNase H-的M-MLV反转录酶。一般的野生型M-MLV (Moloney Murine Leukemia Virus) 具有以下几种活性:依赖于RNA的DNA聚合酶活性;依赖于DNA的DNA聚合酶活性;RNase H活性。由于RNase H能够催化降解DNA/RNA杂合体中的RNA,因此在cDNA第一条链的合成反应中可能会降解RNA/DNA杂合体中的模板RNA。
本酶M-MLV (RNase H-) 的RNase H活性缺失,延伸能力强,可用于较长的cDNA合成以及高比例的全长cDNA文库的构建等。
 
保存
-20℃。
 
起源
Purified from an E.coli strain expressing a recombinant enzyme.
 
活性定义
以Poly (rA)·Oligo (dT) 为模板/引物,在37℃、10分钟条件下,掺入1 nmol的 [3H] dTTP所需要的酶量定义为1个活性单位 (U)。
 
用途
1. 1st-Strand cDNA的合成。
2. cDNA Probe的制备。
3. RT-PCR反应以及Real Time RT-PCR反应。

描述

 

M-MLV (Moloney Murine Leukemia Virus) Reverse Transcriptase (RT) is a recombinant DNA polymerase that synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. Compared to AMV RT, M-MLV RT lacks DNA endonuclease activity and has a lower RNase H activity.

• Thermostability – Optimal activity at 37°C
• Size of cDNA – MMLV can be used to synthesize first-strand cDNA up to 7 kb
• Applications – Synthesis of first-strand cDNA (1), primer extension (2), sequencing dsDNA (3), cDNA libraries, and RT-PCR (4)

Source: Purified from E. coli expressing the pol gene of M-MLV on a plasmid (5).

Performance and Quality Testing: SDS-PAGE purity; endodeoxyribonuclease, exodeoxyribonuclease, and ribonuclease assays; and yield and length of cDNA product.

Unit Definition: One unit of M-MLV RT is the amount of enzyme required to incorporate 1 nmole of deoxyribonucleotide into acid-precipitable material in 10 min. at 37°C using poly(A)•oligo(dT)12-18 as template•primer (6).

Unit Reaction Conditions: 50 mM Tris-HCl (pH 8.3), 40 mM KCl, 6 mM MgCl2, 1 mM DTT, 0.5 mM [3H]dTTP, 0.1 mM poly(A), 0.1 mM oligo(dT)12-18, 0.1 mg/ml BSA, and enzyme in 50 µl for 10 min. at 37°C (6).
