E. coli Ribonuclease H (RNase H), Recombinant


Ribonuclease H (RNase H) is an endoribonuclease which specifically degrades the RNA strand of an RNA/DNA hybrid, leaving the DNA strand and unhybridized RNA intact. E.coli RNase H (=RNaseHI) was over-expressed in E. coli as a recombinant protein and highly purified. MW is 17.6 kDa.


• Removal of mRNA in DNA/RNA hybrid prior to the synthesis of the second strand of cDNA (1, 2)
• Removal of poly (A) tails from mRNA after hybridization with oligo (dT) (3)
• Oligodeoxyribonucleotide-directed site-specific cleavage of RNA
