RNHB-100

RNase H is an endoribonuclease which degrades the RNA strand of RNA/DNA hybrid molecules.

Description
RNase H is an endoribonuclease which degrades the RNA strand of RNA/DNA hybrid molecules. RNase H digestion produces ribonucleotide molecules with 5'-phosphate and 3'-hydroxyl termini. RNAse H is nearly inactive against single or double-stranded RNA molecules.
RNase H from the thermophilic bacterium Bacillus stearothermophilus is thermostable, has optimal activity above 65°C and making it useful for a broad range of applications.

 

Applications

Removal of poly(A) tails of mRNA hybridized to poly(dT)

Removal of mRNA during second strand cDNA synthesis
