title: Purification of ribonuclease T1.
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.
