Immunological Similarities of Proteinase Inhibitors from Potatoes

Abstract
Proteinase inhibitors, purified independently from Japanese, United States and German potato varieties, and having different physicochemical and inhibitory properties, were shown to be immunochemically similar. The heterogeneity found among proteinase inhibitors from potato tubers is apparently due both to intervarietal, as well as intravarietal, variations in isoinhibitor components.
