Purification of ribonuclease T1

Anal Biochem. 1987 Dec;167(2):418-22. doi: 10.1016/0003-2697(87)90186-2.

Abstract

An improved method for purifying ribonuclease T1 from Aspergillus oryzae is described. The method uses gradient elution from DEAE-cellulose and sulfopropyl-Sephadex columns followed by gel filtration on Sephadex G-50 to give almost 100 mg (50% yield) of ribonuclease T1 from 100 g of starting material in less than 5 days.
