Compared to AMV RT, Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV RT) lacks DNA endonuclease activity and has a lower RNase H activity.

  • Thermostability—optimal activity at 37°C
  • Size of cDNA—M-MLV can be used to synthesize first-strand cDNA up to 7kb
  • Applications—synthesis of first-strand cDNA, primer extension, sequencing dsDNA, cDNA libraries, and RT-PCR
  • Source: Purified from E. coli expressing the pol gene of M-MLV on a plasmid
  • Performance and quality testing: SDS-PAGE purity; endodeoxyribonuclease, exodeoxyribonuclease, and ribonuclease assays; and yield and length of cDNA product
  • •Concentration: 200U/μLUnit definition: One unit of M-MLV RT is the amount of enzyme required to incorporate 1nmole of deoxyribonucleotide into acid-precipitable material in 10 minutes at 37°C using poly(A)oligo(dT)25 as template-primer
  • Unit reaction conditions: 50mM Tris-HCl (pH 8.3), 40mM KCl, 6mM MgCl2, 1mM DTT, 0.5mM [3H]dTTP, 0.1mM poly(A), 0.1mM oligo(dT)25, 0.1mg/mL BSA, and enzyme in 50μL for 10 minutes at 37°C

  • Optimal reaction temperature: 37°C
  • Final product size: 7kb or less
