Binding patterns of lectins to human retinoblastoma cells: preliminary findings.

Lectin binding patterns of cultivated retinoblastoma cell lines Y-79 and Mac-7 and freshly isolated tumor tissue revealed membrane-associated sugar residues NAcD-Gal, D-Gal, mannose, and D-GlcNAc. Compared to normal retinal pigment epithelium, LCA positively bound to retinoblastoma cells. Similarities in the glycoconjugate patterns with LV-B-1 cells are shown.
