Specifications
SKU 02101076-CF
Alternate Names Pancreatic Ribonuclease; RNase A; Ribonuclease I; Ribonucleate 3′ pyrimidinooligonucleotidohydrolase
Application Notes Ribonuclease A, and to a greater extent its oligomers and some homologs (such as onconase from frogs), have cytotoxic and cytostatic effects, particularly on cancer cells.This attribute has led to the development of onconase as a cancer therapeutic.
Base Catalog Number 101076
Biochemical Physiological Actions Ribonuclease A is an endoribonuclease that cleaves single stranded RNA after pyrimidine nucleotides. It attacks at the 3’ phosphate end. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2'-OH groups essential for the formation of cyclic intermediates. RNase can also hydrolyze RNA from protein samples. RNase A can be inhibited by alkylation of His12 and His119 and activated by potassium and sodium salts.
