MMLV Reverse Transcriptase (for RT-PCR), encoded by Moloney Murine Leukemia Virus (MMLV RT) is an RNA-dependent DNA polymerase that synthesizes the complementary cDNA first strand from a single-stranded RNA template to which a primer has been hybridized
AMV Reverse Transcriptase, encoded by Avian Myeloblastosis Virus reverse transcriptase and expressed in E.coli. is an RNA-dependent DNA polymerase that synthesizes the complementary cDNA first strand from a single-stranded RNA template
Tth DNA Polymerase Maximo is used to reverse-transcribe RNA efficiently in the presence of manganese. PCR can be performed in the same tube using the intrinsic DNA polymerase activity simply by chelation of manganese cation and the addition of magnesium.
