Genta benzonuclease, >99%, 250,000 units/ml

Genta benzonuclease is a nuclease that cleaves all types of both DNA and RNA (single-stranded, double-stranded, linear and annular) to form oligodeoxynucleotides with terminal 5’-monophosphates 3-5 bases long. It is effective in a wide range of working conditions. It has no proteolytic activity.

Isolated from a strain of Escherichia coli expressing the nuclease gene from the microorganism Serratia marcescens.

Reaction conditions: 20 - 37 °C, optimal buffer: 50 mM Tris-HCl (pH 8.0 at 25 °C); 100 -150 mm NaCl; 1 mM MgCl2.
