The effects of glutaraldehyde, formaldehyde, or osmium tetroxide fixation on the number of labeled Con A surface receptors on mouse peritoneal macrophages were compared. Gold-labeled Con A receptors were found to be isolatedly arranged and evenly distributed on cell surfaces independent of the fixative used. Only cells preincubated with Con A and(More)
A standardless X-ray microanalytical procedure has been developed to determine the number of gold-labelled surface receptors on whole single cells. The effect of the injection of K2PtCl4 into mice on gold-labelled concanavalin A (Con A) receptors on peritoneal macrophages was examined with an energy dispersive X-ray detector in an SEM. The numbers of gold(More)
Receptors binding of low-density lipoprotein at surfaces of human lymphocytes was studied by immunochemical and scanning electron microscopical methods. Using colloidal gold sol binding ability of cells from several probands could be demonstrated by immunolabelling. We investigated cell material from normolipidaemic persons and from patients with(More)
