The five DEAE chromatographic fractions (II, III, IV1, IV2, V) of soybean trypsin inhibitor were less stable in heated alkaline solutions than in acid solutions. Cystine-poor fractions II and III were the most heat- stable inhibitors in acid solutions, while cystine-rich fractions IV1 and IV2 possessed an intermediate stabilty. Cystine-moderate fraction V, which was identified as Kunitz-inhibitor and SBTIA2, was found to be the most heat-unstable inhibitor.
