1. An elastase-like enzyme was purified from the pyloric caeca of rainbow trout by hydrophobic interaction, cation exchange and gel-filtration chromatography. 2. The approximate molecular weight of the elastase was 27 kDa and the isoelectric point was remarkably basic. 3. The pH optimum of this enzyme was 8.0, when assayed with Succinyl-Ala-Ala-Ala...

Past work has shown that a subset of effector T cells with unique characteristics could abrogate hapten- or antigen-induced tolerance, and the reconstitution of this immune response has been termed contrasuppression. We have studied contrasuppression in a model of oral tolerance (OT) in which adoptively transferred antigen-specific T contrasuppress...
Two chymotrypsins, called chymotrypsin I and II, were purified from the pyloric caeca of rainbow trout, by (NH4)2SO4 fractionation, hydrophobic interaction chromatography (phenyl-Sepharose) and ion-exchange chromatography (DEAE-Sepharose). The approximate molecular weights of chymotrypsin I and II were 28,200 (.+-.1200) and 28,800 (.+-.900), respec...
