AMV Reverse Transcriptase Avian Myeloblastosis Virus (AMV) Reverse Transcriptase is an RNA directed DNA polymerase which can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template.Description:• The enzyme is purified from a recombinant source.• The only clone truly derived from the Avian Myeloblastosis Virus.• Maintains the RNA- and DNA-dependent DNA polymerase and RNase H activities.• RNase H activity can be regulated over a wide range of temperatures.• Expressed as a very stable, highly active polymer.• Remarkably robust in cDNA synthesis and RT-PCR.• Capable of synthesizing cDNA over a wide range of temperatures.• Ideal for use in RT-PCR, cDNA libraries, RAMP™, NASBA™ and dideoxy-DNA sequencing (1,2,3).Unit Definition: One unit is the amount of enzyme required to incorporate 1 nmol of dTTP into acid-insoluble form in 10 min at 37oC (4).Storage Conditions: Store at –20oC.Storage Buffer: 200 mM potassium phosphate (pH 7.2), 2% (v/v) Triton™X-100 and 50% (v/v) glycerol.Assay Conditions: 50 mM Tris-HCl (pH 8.3 at 22oC), 6 mM MgCl2, 40 mM KCl,1 mM dithiothreitol, 0.2 mM poly(rA)·(dT)50, 0.5 mM [3H]dTTP in a reaction volume of 50 µl.Quality Control: All preparations are assayed for contaminating endonuclease and exonuclease and nonspecific RNase and single- and double- stranded DNase activities.References:1.
