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. WebPrior treatment with RNase A (digests single stranded RNA) does not affect the IP signal whereas prior treatment with RNase H (digests RNA in DNA-RNA hybrids) eliminates the signal. The pCALM3_2 vector used to generate R-loops was kindly provided by Prof. Frederic Chedin at UC Davis.
