Quantitation of [formula omitted] sites on the surface membrane of normal and transformed mammalian cells

Abstract

Measurements of the binding of 125I-labeled soybean agglutinin to cells cultured with fetal calf serum have shown, that there can be a similar number of d-GalNAc-like sites exposed on normal and transformed mouse and rat cells; that there were only 10 % of such sites on transformed hamster cells; and that treatment with pronase can render normal cells agglutinable by soybean agglutinin without increasing the total number of exposed d-GalNAc-like sites.
