Description

ThermoPlus M-MLV Reverse Transcriptase(RNase H-),encoded by Moloney Murine Leukemia Virus (M-MLV 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. thermol plus MMLV is a mixture of several temperature-resistant reverse transcriptase enzymes with good temperature adaptability. The optimal temperature range is 50-60 ℃, adapting to a variety of different reaction conditions. It has excellent reverse transcription performance.

Source

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

Concentration

200U/μl

Features

1. Lack RNase H activity: Weak RNaseH activity High cDNA yield, can get more full length cDNA.
2. Thermal stable: the optimum reaction temperature is 50℃,the highest is 60℃. Can overcome the template RNA secondary structure ,and finish the reverse transcriptase experiment smoothly.
3. Wide temperature range: can reverse transcript from 37-60C,with more than 80% of the highest activity at 42℃-55℃ customer can choose the reaction temperature freely.
4. 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.

Application

The first-strand cDNA synthesis; RT-PCR.
