原裝現(xiàn)貨|SUPERSCRIPT II
描述:
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 cDNA – Generation of RT-PCR products up to 12 kb
Thermostability – Full activity at 42°C
Flexibility – Uses either total or poly(A)+ RNA
