Effects of antisera raised against native and denatured human alpha-glucosidase and beta-hexosaminidases on native enzyme activity.
Antisera were raised in rabbits against native and sodium dodecylsulfate denatured forms of human acid alpha-glucosidase and beta-hexosaminidases A and B. Anti-native enzyme antisera were able to precipitate all or nearly all enzyme activity from cell extracts, and to eliminate all stainable activity on electrophoresis. Antisera prepared against denatured enzymes precipitated only a minor part of enzyme activity. Electrophoretic analysis showed that these antisera were able to bind to the enzyme molecule. The result was a slowing down of the anodic migration but not immobilization. The use of variants with hexosaminidase deficiencies helped to clarify the action of the antisera on the various hexosaminidase isozymes.
