Synonym: Pancreatic Ribonuclease
Ribonuclease I
Ribonucleate 3’-pyrimidinooligonucleotidohydrolase
RNase A
CAS Number: 9001-99-4
(EC) Number: 3.1.27.5
Descriptions:
Analysis Note: Protein determined by E1%/280.
Application: RNase protection assays
Remove unspecifically bound RNA
Analysis of RNA sequences
Hydrolyze RNA contained in protein samples
Purification of DNA
Pancreatic RNase A specifically cleaves at the 3’-side of pyrimidine (uracil or cytosine) phosphate bonds. 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.
Preparation Note: Salt fractionated and chromatographically purified.
