M-MuLV Reverse Transcriptase RNase H+
Detailní popis
Thermo Scientific M-MuLV Reverse Transcriptase (RT) is an RNA- and DNA-dependent DNA polymerase. It can use either RNA or DNA to prime DNA synthesis. The enzyme possesses a ribonuclease H activity specific to RNA in RNA-DNA hybrids (see References 1, 2).
Highlights
- High yields of first strand cDNA up to 9 kb
- Optimum activity at 37°C
- Incorporates modified nucleotides (e.g., Cy3-, Cy5-, rhodamine-, aminoallyl-, fluorescein-labeled nucleotides)
Applications
- First strand cDNA synthesis for RT-PCR and real-time RT-PCR
- Synthesis of cDNA for cloning and expression
- Generation of labeled cDNA probes for microarrays
- DNA labeling (see Reference 3)
- Analysis of RNA by primer extension (see Reference 3)
Includes
- M-MuLV Reverse Transcriptase (20 U/μL)
- 5X Reaction Buffer
Note
M-MuLV RT has significantly lower RNase H activity than Avian Myeloblastosis Virus (AMV) reverse transcriptase.
