S1 Nuclease
Endonuclease Specific for Single-Stranded DNA and RNA
- Enzyme yields 5´-phosphoryl-terminated products
- Double-stranded nucleic acids (DNA:DNA, DNA:RNA or RNA:RNA) resist degradation except with extremely high concentrations of enzyme
- Supplied at a concentration of 20–100u/μl

S1 Nucleaseは、一本鎖DNA、RNAをエンドヌクレアーゼ様に分解し、5′-末端にリン酸基を持つ分解産物を生成します。極めて高濃度な場合を除き、二本鎖核酸(DNA:DNA, DNA:RNA, RNA:RNA)には作用しません。
- 10X Reaction Buffer 添付:0.5M sodium acetate (pH4.5 at 25°C), 2.8M NaCl, 45mM ZnSO4
- 二本鎖DNA末端から突出している一本鎖部位を除去
- 一本鎖DNAの選択的切断
- RNA転写産物のマッピング
