Product description

M-MLV cDNA Synthesis Kit is designed for the highest efficiency conversion of RNA to cDNA. Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV RT) is a RNAdirected DNA polymerase that can synthesize a complementary DNA (cDNA) strand from a primer hybridized to either RNA or single stranded DNA as a template. M-MLV Reverse Transcriptase is capable of synthesizing DNA longer than 5 kb from messenger RNA. RNase H activity of M-MLV Reverse Transcriptase is weaker than that of Avian Myeloblastosis Virus (AMV) Reverse Transcriptase. M-MLV Reverse Transcriptase does not possess 3′→5exonuclease activity. A two-step RT-PCR format is useful for amplifying multiple targets from a single cDNA source, for maintaining archival cDNA, and for providing maximum flexibility in selecting a downstream qPCR reagent system.

Unit definition

One unit is defined as the amount of enzyme required to incorporate 1 nmol of dTTP into acid-insoluble materrials using 0.4 mM poly(rA)-oligo(dT) as substrate at 37 in 10 min in a 1X reaction buffer.

 

 

Standard reaction conditions

RNase Inhibitor (40 units/μl)

0.5 μl

Sterile water (RNase free)

up to 20 μl

a)Prepare one of the following RNA template.

    - Total RNA: 1 ng~5 μg

    - Messenger RNA (mRNA): 1 ng~250 ng

    - Specific RNA: 0.01 pg~0.5 μg

b)Prepare one of the following primers.

    - Oligo (dT)18: 50 μM~100 μM

    - Random hexamer: 50 μM~100 μM

    - Specific primer: 15 pmol~20 pmol

An additional annealing step is recommended:

    - if using oligo(dT)18, incubate at 42 for 5 min.

    - if using random hexamer, incubate at 25 for 10 min.

Incubate at 37℃ or 42 for 60 min.

Incubate at 95 for 5 min to inactivate the reaction.
