RNase H (Ribonuclease H), E. coli is an endoribonuclease that specifically hydrolyzes the phosphodiester bonds of RNA strands in RNA-DNA hybrids. This enzyme cleaves the 3'-O-P-bond of RNA and generates 3' hydroxyl and 5' phosphate products. RNase H does not digest single-stranded or double-stranded DNA and RNA.
Description
Removal of the poly(A) sequences from mRNA in the presence of oligo (dT) ; Directed cleavage of RNA ; Note: This product is not suitable for NGS or second strand cDNA synthesis applications.
Notes
One unit is defined as the amount of RNase H, E. coli that is required to hydrolyze 1 nmol of the RNA in radiolabeled poly(rA):poly(dT), to acid-soluble ribonucleotides in a total reaction volume of 50 μl in 20 minutes at 37°C in 1X RNase H, E. coli Reaction Buffer with 10 nmol radiolabeled poly(rA) and 12.5 μg poly(dT).
