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

Description

10,000u
Catalog number: M5761

S1 Nuclease is an endonuclease that degrades ssDNA and RNA. The enzyme is used to remove protruding single-stranded termini from double-stranded DNA, for selective cleavage of single-stranded DNA and for mapping RNA transcripts. S1 Nuclease is provided with 10X Reaction Buffer: 0.5M sodium acetate (pH 4.5 at 25°C), 2.8M NaCl, 45mM ZnSO4.
