[Alpha-glucosidase from human kidneys].
The data obtained show that most part of the activity of neutral alpha-glucosidases from human kidney is observed in the particle fraction, and only approximately 15%--in supernatant. Soluble neutral alpha-glucosidases have at least 4 different forms, as it is shown by means of their fractionation on Sephadex G-150, Bio-Gel P-200 and by polyacrylamide gel electrophoresis. Four forms are different in their molecular weight, electrophoretic mobility and substrate specificity. Two of the forms have molecular weight of 310000 and 110000. All the neutral alpha-glucosidases except high molecular weight form (greater than 400000) were retarded on column of Sephadex G-150.
