Description
The  Medico M-MLV Reverse Transcriptase (RT) is a genetically modified  M-MLV RT. It differs from the M-MLV RT by its structure and catalytic  properties. The enzyme possesses an RNA-dependent and DNA-dependent  polymerase activity and a ribonuclease H activity specific to RNA in  RNA-DNA hybrids. Dongsheng M-MLV Reverse Transcriptase has significantly  lower RNase H activity than Avian Myeloblastosis Virus (AMV) reverse  transcriptase.

Source
E.coli cells with a cloned fragment of the pol gene encoding Moloney Murine Leukemia Virus reverse transcriptase.

Applications
Generation of first strand cDNA for use in:
PCR, see Protocol for First-strand cDNA Synthesis;
real-time PCR;
second strand cDNA synthesis;
DNA labeling;
Analysis of RNA by primer extension.

Quality Control
The  absence of endodeoxyribonucleases, exodeoxyribonucleases, phosphatases  and ribonucleases confirmed by appropriate quality tests.
Functionally tested in first strand cDNA synthesis.
