Detail View


M-MLV RT (Molony Murine Leukemia Virus Reverse Transcriptase) is an RNA-dependent DNA polymerase requiring a DNA primer and an RNA template to synthesize a complementary DNA strand. M-MLV RT has a weaker intrinsic RNase H activity than AMV RT (Avian Myeloblastosis Virus Reverse Transcriptase). Purified from an E. coli strain carrying a M-MLV RT overproducing plasmid.
