Galactosyltransferase and concanavalin A agglutination of cells.
A correlation has been observed between concanavalin A agglutination of various cell types and the presence of surface membrane galactosyltransferase (1-O-alpha-D-Galactosyl-myo-inositol:raffinose galactosyltransferase, EC 2.4.1.67) activity. Moreover, a reduction to less than 50% of cell surface galactosyltransferase activity occurred after treatment with concanavalin A; other cell surface gly...
متن کاملRole of cell membrane galactosyltransferase in concanavalin A agglutination of erythrocytes.
It has been previously observed that rabbit erythrocyte cell surface galactosyltransferase appears to play a role in concanavalin A agglutination of these erythrocytes (Podolsky et al., 1974). Further, a correlation between the occurrence or level of cell surface galactosyltransferase and concanavalin A agglutinability of other cell types has also been observed. The mechanism by which rabbit er...
متن کاملAgglutination of Japanese encephalitis virus with concanavalin A.
Results of experiments have indicated that reduction in biological activities at high concentrations of Japanese encephalitis virus is caused by aggregates of the virus by concanavalin A. The possibility exists that the concanavalin A binding site is different from hemagglutination and antireceptor sites of Japanese encephalitis virus.
متن کاملA quantitative assay for concanavalin A-mediated cell agglutination.
A quantitative method was developed for measuring cell agglutination by the plant lectin, concanavalin A. The method, based on an assay for intercellular adhesion, determines the concanavalin A-stimulated rate of attachment of single cells to a cell layer. The rate depended on the number of single cells and the concentration of concanavalin A. Experiments on concanavalin A agglutinability of mo...
متن کاملConcanavalin A-mediated agglutination of 3T3 cells after exposure to UV-irradiated herpes simplex virus.
Studies were made to determine the effect of UV-irradiation of herpes simplex virus (HSV) on Concanavalin A (Con-A)-mediated agglutination of 3T3 cells. There were three different phases of agglutination by Con-A of cells infected with HSV. The agglutinability began to increase from 3 or 4 hr, or 72 hr after exposure of cells to HSV. The early-appearing agglutinability was further divided into ...
