M-MLV Reverse Transcriptase

Moloney Murine Leukemia Virus enzyme & buffer for cDNA synthesis

Synonym: Moloney Murine Leukemia Virus Reverse Transcriptase




M-MLV (Moloney Murine Leukemia Virus) reverse transcriptase is a DNA polymerase that uses single-stranded RNA, DNA, or an RNA-DNA hybrid (using a primer) to synthesize a complementary DNA strand. M-MLV is used for the preparation of cDNA libraries or for first strand cDNA synthesis for use in RT-PCR reactions.

Features and Benefits

• Thermostable reverse transcriptase active at 37 °C.
• Can be used to generate first strand cDNA of up to 7 kb.


Supplied with 10× M-MLV reverse transcriptase buffer containing DTT.

Preparation Note

The enzyme is purified from Escherichia coli expressing the pol gene of M-MLV on a plasmid.

Legal Information

Purchase of this product is accompanied by a limited license for use in the Polymerase Chain Reaction (PCR) process for research purposes only and in conjunction with a thermal cycler whose use in the automated performance of the PCR process is covered by an up-front license fee, either by payment to Applied Biosystems or as purchased, i.e., and authorized thermal cycler.

Unit Definition

One unit incorporates 1 nmol of TTP into acid precipitable material in 10 min. at 37 °C using poly(A):oligo dT as a template:primer.
