Ribonucleases

AbstractRibonucleases (RNases) with different sequence specificities are used for a variety of analytical purposes, including RNA sequencing, mapping, and quantitation. One very common application for RNase A is presented in this unit and involves hydrolyzing RNA that contaminates DNA preparations. Two other commonly used RNases, RNase H and RNase T1, are also described. In addition, many commercially available RNases are sequence‐specific endoribonucleases, a property has been used for enzymatic sequencing of RNA.
