Summary

Bovine, ovine and caprine pepsin and lamb, piglet and kid chymosins (rennins) were isolated by basically the same procedure of selective pH precipitation, DEAE-cellulose chromatography in phosphate buffer, pH 6·5 and Sephadex G-100 chromatography. The homogeneity of the preparations was assessed by (a) re-cycling on Sephadex G-100, (b) chromatography on DEAE-cellulose using piperazine buffer, pH 5·3 and (c) ability to inactivate ribonuclease.
