biotechrabbit™ MMuLV Reverse Transcriptase is an exceptionally pure DNA polymerase which uses RNA as a substrate and exhibits no measurable proofreading 3'→5' exonuclease function. This enzyme performs cDNA synthesis by extending a DNA primer annealed to an RNA template; it can also make copies from a single-stranded DNA templates.
The enzyme is purified from a recombinant E. coli strain carrying the MMuLV reverse transcriptase gene.
