DESCRIPTION
AMV (Avian Myeloblastosis Virus) Reverse Transcriptase is an RNA-dependent DNA polymerase. This enzyme catalyses the polymerization of DNA using single-stranded DNA or RNA as a template in the presence of a primer. It also has a 3' → 5' RNase H activity that degrades the RNA portion of RNA-DNA hybrids.

SOURCE
Purified from Avian Myeloblastosis virus.

APPLICATIONS
● cDNA synthesis.
● DNA sequencing by dideoxy method.
● RNA sequencing.
● 3'-end labeling of DNA fragments.
