| Abstract: | The synthesis and localization of chick acid alpha-glucosidase has been studied in chick erythrocyte-human fibroblast heterokaryons. Monospecific antibodies raised against purified chick liver acid alpha-glucosidase were used. It was found that the acid alpha-glucosidase in the heterokaryons is of chick origin, and is localized in the same lysosomes as the human lysosomal enzymes. It is concluded that chick erythrocyte-human fibroblast heterokaryons provide a useful model system for the study of lysosomal enzyme synthesis and routing. |
