Discrimination of MUC 1 Mucins from Other Sialyl-Lea-carrying Glycoproteins Produced by Colon Carcinoma Cells Using a Novel Monoclonal Antibody 1

Abstract

Earlier studies (Baeckström et al., J. Biol. (han.. 266: 21537-21547, 1991 ) have revealed that the colon carcinoma cell line COLO 205 produces two different proteins carrying the carcinoma-associated sialyl-Le" carbo hydrate epitope. One is the MUC1 mucin apoprotein, and the other pro tein is smaller and has not been characterized in detail. This paper de… (More)
