M-MLV Reverse Transcriptase (RNaseH-)
- Supports reverse transcription in a wide temperature range (37-60°C)
- Guaranteed high purity, free of nuclease contamination and residual bacterial DNA
- Work efficiently with GC-rich and highly structured RNA templates
- Long-range PCR to amplify RNA up to 10kb
- Also available in a glycerin-free form for freeze-dried qPCR
M-MLV ( Moloney Murine Leukemia Virus ) reverse transcriptase (RNaseH-)is an RNA-directed DNA polymerase. This enzyme can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template. M-MLV reverse transcriptase lacks 3´ → 5´ exonuclease activity and RNase H activity.
Storage and transportation: Storage at -20 ℃ and transportation≤0℃
Supplied in: 50 mM Tris-HCl(pH 7.6 at 25℃), 150 mM NaCl, 0.1 mM EDTA, 1 mM dithiothreitol, 0.1% IGEPAL CA-630 and 50% Glycerol.
Unit definition: One unit incorporates 1 nmol of dTTP into acid-precipitable material in 10 minutes at 37°C using poly(A)•oligo(dT)25 as template-primer.
Quality Control Assays
- Endonuclease Activity: Incubation of 400 U of enzyme with 4 μg pUC19 DNA for 4 hours at 37°C resulted in no detectable degradation of the DNA as determined by gel electrophoresis.
- Exonuclease Activity: Incubation of a 50 µl reaction containing a minimum of 500 U of enzyme with 10 nM 5´-FAM oligonucleotide for 30 minutes at 37℃ yields no detectable degradation.
- RNase Activity: Incubation of a 10 µl reaction containing 400 U of enzyme with 1μg of MS2 RNA transcripts for 1 hour at 37°C resulted in no detectable degradation of the RNA as determined by gel electrophoresis.
