Will be supplied as "M-MLV RT GMP Grade, 200 KU". Unit of measure is "piece".
The enzyme is supplied without reaction buffer.
M-MLV Reverse Transcriptase for preparation of full-length cDNA with high efficiency.
Use M-MLV Reverse Transcriptase for synthesis of cDNA from total RNA or mRNA for:
  • Two-step RT-PCR applications for amplification from RNA targets
  • RT-PCR for detection of viral RNA
  • TMA and NASBA nucleic acid amplification methods
  • Synthesis of full-length cDNA for libraries or cloning
  • Rapid amplification of cDNA end (RACE)
  • Manufacture of amplification mixtures for applications with regulatory requirements (e.g., in vitro diagnostics, quality control)
M-MLV Reverse Transcriptase, GMP Grade, is highly processive and generates full length cDNA with high efficiency. It has a lower RNase H activity than AMV Reverse Transcriptase and lacks endonuclease activity.
