Description

Ribonuclease B is used to remove RNA from DNA plasmid preparations and protein samples. Ribonuclease B is used for RNase protection assays, to remove unspecifically bound RNA, analysis of RNA sequences, to hydrolyze RNA contained in protein samples, and the purification of DNA. Ribonuclease B from bovine pancreas has been used in a study to assess hybridase activity of human ribonuclease-1. Ribonuclease B from bovine pancreas has also been used in a study to investigate particle-based and monolithic columns for cation exchange protein displacement chromatography.
