背景介绍

  • Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV RT) is an RNA-dependent DNA polymerase. The enzyme can use RNA (when synthesizing cDNA) or single-stranded DNA as a template and initiate the synthesis of a complementary DNA strand from a primer. M-MLV reverse transcriptase has no 3´ → 5´ exonuclease activity.

产品组分

  • Storage Solution : 200 U/ul M-MLV Reverse Transcriptase、50 mM Tris-HCl、150 mM NaCl、1 mM DTT、0.1 mM EDTA、50% Glycerol、0.1% NP-40、pH 7.6 @ 25°C
    10*Reaction Buffer: 500 mM Tris-HCl、750 mM KCl、30 mM MgCl2、100 mM DTT(pH 8.3 @ 25°C)

操作步骤

  • 1. Genomic DNA was removed from the extracted cell total RNA by DNase I.
    2. After incubating at 37 °C for 30 minutes, add 1µl 0.5 M EDTA (to the final concentration of 5mm) and inactivate at 75°C for 10 minutes.
    3. Mix RNA sample, Random Primer and 1 ul M-MLV Reverse Transcriptase in a sterile RNase-free microfuge tube.
    4. Incubate the 20 μl cDNA synthesis reaction was incubated at 25℃ for 5 minutes and then at 42℃ for 1 hour.
    5. Inactivate the enzyme at 65°C for 20 minutes. The cDNA product can be directly fed into the qPCR reaction or stored at -20°C.

注意事项

  • Please avoid repeated freeze-thaw cycles.

酶活定义
  • 1 unit refers to the amount of enzyme required to catalyze the incorporation of 1 nmol of dTTP into acid-insoluble matter in 10 minutes in a 50μl total reaction system containing 50 mM Tris-HCl (pH 8.3), 6 mM MgCl2, 10 mM dithiothreitol, 0.5 mM [3H]-dTTP and 0.4 mM poly(rA). oligo(dT)12-18 at 37°C, using poly(rA). oligo(dT) as the template primer.

  • 生物活性

    • The nucleic acid glue map shows the effect of M-MLV reverse transcriptase on total RNA for qPCR detection. The total RNA extracted from HEK293T cells was 2µg. In 20μl reverse transcription system (1µg Total RNA, 120uM Random Hexamer primer, 1X Reaction Buffer, 20U RNase Inhibitor, dNTP Mix (1mM each), After retrotranscription, 1μl of the retrotranscription product was obtained for qPCR amplification and electrophoresis detection of 197bp segment of β-actin cDNA. As shown in the figure, this product has comparable enzyme activity compared with Competitor N's products.
