โฆ Synopsis
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.

Purification of ribonuclease T, has been achieved using a porous glass-2',(3')-GMP affinity adsorbent. This adsorbent cshibits specific affinity for ribonuclease T, and is almost devoid of non-specific ion-eschange properties. \_.~.\_.. .\_.
