    Avoiding RNase Contamination
Moloney Murine Leukemia Virus (M-MuLV, MMLV) Reverse Transcriptase is an RNA-directed DNA polymerase. This enzyme can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template. (1-4). M-MuLV Reverse Transcriptase lacks 3´ → 5´ exonuclease activity.
Product Source
The gene encoding M-MuLV Reverse Transcriptase is expressed in E. coli in a vector that results in 16 additional amino acids at the N-terminus and 13 amino acids at the C-terminus. This construct results in a fully functional Reverse Transcriptase protein with a functional RNase H domain.
