M-MLV RTase (M-MLV Reverse Transcriptase)
Moloney Murine Leukemia Virus (M-MLV) Reverse Transcriptase is an RNA-dependent DNA polymerase that synthesizes the first strand of complementary cDNA from a single-stranded RNA template with hybridized primer. This kit features high activity formulation of M-MLV RT and 5X reverse transcription buffer which are capable of full-length cDNA synthesis and high cDNA yields.

First strand cDNA synthesis:
1. Place all required reagents to a nuclease-free microcentrifuge tube and following the order suggested below.
2. Heat the tube to 65°C for 10 minutes to denature the secondary structure within RNA template. Immediately cool the tube on ice for 1 minute and centrifuge briefly in microcentrifuge. Add the following components to the annealed primer/RNA template, prepare on ice.
3. Incubate at 37°C for 1 hour. The extension temperature may be adjusted from 37°C to 42°C.
4. Inactivate the reaction at 65°C for 20 minutes. The cDNA products should be store at -20°C.
5. Reaction preparations may be scaled up or down proportionately.
