The results of a detailed comparison of the relative efficiencies of different procedures for solubilizing the membrane-bound α-glucosidases in hog intestinal mucosa are reported. Procedures for the selective solubilization of certain members of the complex group of α-glucosidases have been developed. The selective solubilization achieved permits the conclusion that separate α-glucosidases are involved in the hydrolysis of isomaltose and the α-limit dextrins formed from starch by α-amylase.
