摘要：
A rabbit was immunized with the purified alpha-amylase inhibitor from cranberry beans to obtain a specific antiserum. With respect to antigenicity, the inhibitor was examined for its distribution in leguminous seeds, and was proved to occur exclusively in cultivars of the same kind (Phaseolus vulgaris) but not in those of other kinds. IN addition, its in-vitro digestibility was investigated by the use of porcine and bovine enzymes. Consequently it was revealed that the inhibitor underwent a gradual inactivation by chymotrypsin digestion (but not by pepsin and trypsin digestions) and that its antigenicity was removed more slowly than its inhibitor activity.
