WebRNase H. RNase H (Ribonuclease H) is an endoribonuclease that specifically hydrolyzes the phosphodiester bonds of RNA, when hybridized to DNA. Recombinant enzyme supplied with Reaction Buffer. Tested for the absence of endonucleases, ss-DNase and other RNases. This enzyme does not digest single or double-stranded DNA. WebRNase A-type enzymes rely on active site histidine residues for catalytic activity (1) and can be inactivated by the histidine-specific alkylating agent diethyl pyrocarbonate (DEPC). Sources of RNase Contamination RNases are found in all cell types and organisms from prokaryotes to eukaryotes.
