Description
Catalog number
RNase ONE™ Ribonuclease is a 27kDa periplasmic enzyme from E. coli that catalyzes the degradation of RNA to cyclic nucleotide monophosphate (NMP) intermediates. Slower hydrolysis further catalyzes the degradation of these intermediates to 3´-NMPs. RNase ONE™ Ribonuclease may be used to remove RNA from DNA preparations, for mismatch detection, RNase protection assays and mapping, or quantitation of RNA by selective cleavage of single-stranded regions. The enzyme is provided with 10X Reaction Buffer: 100mM Tris-HCl (pH 7.5 at 25°C), 50mM EDTA, 2M sodium acetate.
