An oviducal enzyme isolated by affinity chromatography which acts upon the vitelline envelope of Bufo arenarum coelomic oocytes.
A trypsin-like oviducal proteinase acting upon the vitelline envelope of Bufo arenarum coelomic oocytes has been purified to apparent homogeneity by gel filtration on Sephadex G-200 and by affinity chromatography on a column of Sepharose 4-B containing covalently bound concanavlin A (Con A). The biologically active molecule migrated as a single band of protein upon SDS polyacrylamide gel electrophoresis.
