Thermo Scientific™ S1 Nuclease (100 U/μL)
Degrade single-stranded DNA and RNA with this endonuclease.
Supplier: Thermo Scientific™ EN0321
Description
S1 Nuclease degrades single-stranded nucleic acids, releasing 5'-phosphoryl mono- or oligonucleotides. It is five times more active on DNA than on RNA . S1 Nuclease also cleaves dsDNA at the single-stranded region caused by a nick, gap, mismatch or loop. S1 Nuclease exhibits 3'-phosphomonoesterase activity.
The enzyme is a glycoprotein with carbohydrate content of 18%.
- Source: Aspergillus oryzae
- Molecular Weight: 29 kDa monomer
- The absence of contaminating double-stranded DNA specific nuclease activity confirmed by appropriate quality test
- Functionally tested for the generation of unidirectional deletions in DNA fragments (in conjunction with Exonuclease III)
- Aspergillus oryzae
- 29 kDa monomer
- One unit of the enzyme produces 1μg of acid soluble deoxyribonucleotides in 1 min. at 37°C
- Enzyme activity is assayed in the following mixture: 30 mM sodium acetate (pH 4.5), 50 mM NaCl, 0.1 mM ZnCl2, 5% (v/v) glycerol, 800μg/ml heat denatured calf thymus DNA
- The enzyme is supplied in:20mM Tris-HCl (pH 7.5), 50mM NaCl, 0.1mM ZnCl2 and 50% (v/v) glycerol
- 200mM sodium acetate (pH 4.5 at 25°C), 1.5M NaCl and 10 mM ZnSO4
- Inhibitors: metal chelators, PPi, Pi, 5'-ribonucleotides and deoxyribonucleotides
- Inactivated by heating at 70°C for 10 min. in the presence of EDTA
Recommended for:
Removal of single-stranded overhangs of DNA fragments (2); S1 transcript mapping (3, 4); Cleavage of hairpin loops; Creation of unidirectional deletions in DNA fragments in conjunction with Exonuclease III (5)
Note:
S1 Nuclease can introduce breaks into double-stranded DNA, RNA and DNA/RNA hybrids at high enzyme and low salt concentrations (6).
