✦ Synopsis
A microadhesion assay that allows the quantitative determination of carbohydrate-mediated cell adhesion to glycoconjugates immobilized on 96-well polystyrene plates has been developed. After dislodging nonadherent cells by centrifugation, specifically bound cells are quantified by colorimetric analysis of a blue formazan product generated from the dye 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide by enzymatic reduction. Carbohydrate specificity of the cell adhesion was demonstrated by inhibition analyses and the general applicability of the assay was proved with indicator cells of three different origins: mouse fibrosarcoma cells, Chang liver cells, and human breast carcinoma cells (MDA-MB 231).
