INVITROGEN反轉錄酶II，SuperScript II Reverse Transcript
INVITROGEN反轉錄酶II，SuperScript II Reverse Transcriptase貨號18061014
描述
反轉錄（RT）superscript®II是一個改進版本superscript®RT。It is a聚合酶，DNA鏈synthesizes有互補單鏈RNA從DNA、RNA、DNA雜交。這種酶是轉基因工程by the introduction of點突變in the RNase H活性中心to reduce RNase H活性。這eliminates降解RNA分子結構的變化在*鏈cDNA Synthesis and gives superscript®II RT性能特性上。
INVITROGEN反轉錄酶II，SuperScript II Reverse Transcriptase貨號18061014
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
Performance and Quality Testing: SDS-PAGE purity; endodeoxyribonuclease, exodeoxyribonuclease, and ribonuclease assays; and yield and length of cDNA product.
Unit Definition: One unit of SuperScript® II is the amount of enzyme required to incorporate 1 nmole of deoxyribonucleotide into acid-precipitable material in 10 min. at 37°C using poly(A)•oligo(dT)12-18 as template•primer (3).
Unit Reaction Conditions: 50 mM Tris-HCl (pH 8.3), 40 mM KCl, 6 mM MgCl2, 1 mM DTT, 0.5 mM [3H]dTTP, 0.1 mM poly(A), 0.1 mM oligo(dT)12-18, 0.1 mg/ml BSA, and enzyme in 50 µl for 10 min. at 37°C.
For Research Use Only. Not intended for any animal or human therapeutic or diagnostic use.
