AMV Reverse Transcriptase

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


AMV Reverse Transcriptase (AMV RT) catalyzes the polymerization of DNA using template DNA, RNA or RNA:DNA hybrids.  The enzyme possesses an intrinsic RNase H activity. AMV RT possesses multiple enzymatic activities including RNA- and DNA-directed DNA polymerase, DNA-RNA unwinding activity, a sequence-specific Mn2+-dependent endonuclease and ribonuclease H.

Stability tests / Quality control / Comparison

First-Stand cDNA Synthesis:  First strand cDNAs, of 1.2 kb Control RNA is synthesized using 30 units of enzyme, 1 µg of each template, an oligo(dT) primer and a radiolabelled dNTP. The minimum specification is the production of 120 ng of first-strand cDNA. Full-length cDNA must be observed by gel electrophoresis and autoradiography.

Endonuclease Activity: 1 µg of Type I supercoiled plasmid DNA is incubated with 25 units of enzyme in 50mM Tris (pH8.3), 40mM KCl, 7mM MgCl2, 10mM DTT for one hour at 370C. Following incubation, the supercoiled DNA is visualized on an ethidium bromide-stained agarose gel to verify the absence of visible nicking or cutting.

Nuclease Activity: 50 ng of radiolabelled DNA or RNA is incubated with 25 units of enzyme in 4 mM Tris (pH8.3), 3.2 mM KCl, 0.56 mM MgCl2, 0.8 mM DTT for one hour at 37°C, and the release of radiolabeled nucleotides is monitored by scintillation counting of TCA-soluble material. Passing specifications is <1% release for DNase and <3% release for RNase.
