Streptavidin blotting: a sensitive technique to study cell surface proteins; application to investigate autophosphorylation and endocytosis of biotin-labeled insulin receptors.


Covalent attachment of biotin provides a useful method to label cell surface proteins. Subsequent to biotinylation, the protein can be purified by immunoprecipitation with a specific antibody, followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. After transfer to a membrane by electroblotting, the biotinylated protein can be detected by… (More)
