  • AMV Reverse Transcriptase

    Description

    Avian Myeloblastosis Vi­rus (AMV) Reverse Transcriptase is an RNA-directed DNA polymerase. This en­zyme can synthesize a complementary DNA strand initiating from a primer using RNA (cDNA synthesis) or single-stranded DNA as a template (1-3).

    Highlights

    • Synthesizes cDNA from single-stranded RNA

    Properties and Usage

    Unit Definition

    One unit is defined as the amount of enzyme required to incorporate 1 nmol of dTTP into an acid-insoluble form in 10 minutes at 37°C using poly(rA)-oligo(dT) as template primer.

    Storage Temperature

    -20°C

    Storage Conditions

    0.2 mM potassium phosphate
    2 mM DTT
    50% Glycerol
    0.2% Triton® X-100
    pH 7.2 @ 25°C

    Unit Assay Conditions

    75 mM potassium acetate, 50 mM Tris-HCl (pH 8.3) 8 mM magnesium acetate, 0.5 mM [3H]-dTTP, 0.2 mM poly(rA)•oligo(dT)12–18 and 10 mM DTT.

    Quality Control

    Quality Control Assays

    The following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
    • Endonuclease Activity (Nicking):
      The product is tested in a reaction containing a supercoiled DNA substrate. After incubation for 4 hours the percent converted to the nicked form is determined by agarose gel electrophoresis.
    • Exonuclease Activity (Radioactivity Release):
      The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides.
    • RNase Activity (1 Hour Digestion):
      The product is tested in a reaction containing a RNA substrate.  After incubation for 1 hour there is no detectable degradation of the RNA substrate as determined by gel electrophoresis.

    Notes

    1. Reaction Conditions: Incubate at 37-42°C.
    2. The yield and size of cDNA transcript increases with increasing amounts of RT.
    3. Storage: Once thawed, store at -20°C. Repeated freeze thaw cycles will inactivate the enzyme. Aliquots can be stored for longer periods at -70°C.
