Related Product Information



Ribonuclease H (RNase H) is an endoribonuclease which specifically degrades the RNA strand of an RNA-DNA hybrid to produce 5' phosphateterminated oligoribonucleotides and single-stranded DNA. It is suitable for removing mRNA during second strand cDNA synthesis, removing the poly(A) sequences from mRNA in the presence of oligo(dT), and for oligodeoxyribonucleotide-directed cleavage of RNA. RNase H is purified from E. coli expressing the E. coli RNase H gene on a plasmid.
