General description
Expand™ Reverse Transcriptase is a RNA directed DNA polymerase optimized for amplification of cDNA fragments up to 13.5 kb in a two-step RT-PCR assay. The enzyme is a genetically engineered version of the Moloney Murine Leukemia Virus reverse transcriptase (M-MuLV-RT). A point mutation within the RNase H sequence reduces RNase H activity to undetectable levels. Detectable improvements are obtained with respect to higher amounts of full-length cDNA transcripts and longer transcripts compared to using the native M-MuLV-RT.
Specificity
Heat inactivation: 95 °C for 2 min
Reverse Transcriptase enzyme for RT-PCR reactions up to 3 kb
Reverse Transcriptase enzyme for RT-PCR reactions up to 3 kb
Application
Expand™ Reverse Transcriptase has been used in real-time PCR analysis for conversion of isolated RNA into cDNA. It has also been used in reverse transcription (RT). Expand™ Reverse Transcriptase may also be used for analyzing the sequence of the cDNA and comparing it to the genomic sequence. Important information can be obtained on intervening sequences (introns) and genomic recombinations.
Features and Benefits
- Obtain higher amounts of full-length cDNA transcripts and longer transcripts up to 13.5kb
- No RNase H activity
- Efficiently transcribes total RNA, mRNA, viral RNA and RNA rich in secondary structures
- Ideal for two-Step RT-PCR assay
- Purification of cDNA before PCR reaction is not necessary
Packaging
1 set containing 3 components
