Description

MMLV Reverse Transcriptase, encoded by Moloney Murine Leukemia Virus (MMLV RT) is an RNA-dependent DNA polymerase that synthesizes the complementary cDNA first strand from a single-stranded RNA template to which a primer has been hybridized. MMLV RT will also extend primers hybridized to single-stranded DNA. Second strand cDNA synthesis can be achieved from some mRNA templates without an additional DNA polymerase. The difference between this to the general M-MLV RT is that the capacity to endure the heat is enhanced. It can remain the 100% activity at 50°C, it can also keep more than 80% activity even at 55°C.

Source

Recombination of E. coli containing Moloney murine leukemia virus reverse transcriptase gene from clone of Moloney murine.

Applications

The first-strand cDNA synthesis; RT-PCR

Features

• lack RNase H activity: Weak RNase H activity High cDNA yield, can get more full length cDNA.
• thermoStable: the optimum reaction temperature is 50°C, the highest is 60°C. Can overcome the template RNA secondary structure, and finish the reverse transcriptase experiment smoothly.
• wide temperature range: can reverse transcript from 37-60C, with more than 80% of the highest activity at 42°C-55°C customer can choose the reaction temperature freely.
• Strong amplification activity: Gene mutation enhanced the binding capacity of the enzyme and RNA. Increased the amplification speed, can obtain the quality cDNA, suitable for cDNA library construction.
