Mung Bean Nuclease

Mung Bean Nuclease acts as a preferential DNA and RNA endonuclease, hydrolyzing single-stranded DNA and RNA into 5'-phosphate and 3'-hydroxyl-containing products. If used at very high concentrations, Mung Bean Nuclease is also capable of degrading double-stranded DNA, RNA or DNA/RNA fragments from both ends. Due to its single-stranded DNA and RNA endonuclease activity, Mung Bean Nuclease is often used during transcript mapping, duplex or hybrid DNA and RNA blunt ending, and cDNA preparation. 

Mung Bean Nuclease is supplied in a buffer of 10 mM Tris-HCl (pH 7.5), 0.1 mM zinc acetate and 50% glycerol.
