SuperScript® III Reverse Transcriptase (RT) is a proprietary mutant of SuperScript® II RT that is active at 50°C and has a half-life of 220 minutes, providing increased specificity with Gene-Specific Primers (GSPs) and the highest cDNA yield of all RTs. It is ideal for RT-PCR of a specific gene or generating cDNA from total or poly (A) + RNA sample. Like SuperScript® II, it synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. SuperScript® III RT is genetically engineered by the introduction of point mutations that increase half-life, reduce RNase activity...

SuperScript® II Reverse Transcriptase

Category: Products & Services > Proteins, Enzymes, & Peptides > Enzymes > Reverse Transcriptase

SuperScript® II Reverse Transcriptase (RT) is an improved version of SuperScript® RT. It is a DNA polymerase that synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. This enzyme is genetically engineered by the introduction of point mutations in the RNase H active center to reduce RNase H activity. This structural modification eliminates degradation of RNA molecules during first-strand cDNA synthesis and gives SuperScript® II RT superior performance characteristics. • Yield – Reduced RNase H activity results in greater first-strand cDNA yields • Size of ...
