Abstract
Cell surface alteration was studied in a subline of murine lymphocytic leukaemia resistant to the broad-spectrum anticancer agent adriamycin (P388/ADR) employing concanavalin A(Con A)-induced agglutination and rearrangement of lectin receptors. Con A induced more agglutination of P388/ADR when compared to the drug-sensitive parental cell line (P388/S). Studies on the redistribution of Con A and Ricinus communis agglutinin-I revealed a high percentage of P388/ADR showing internalized fluorescence, while a majority of P388/S displayed a uniform distribution of fluorescence on the cell surface.
