Cationic gold colloid
Springer Online Journal Archives 1860-2000
Summary A new one-step incubation method using cationic gold colloid was applied to reveal anionic moieties in rat colonic mucosa. Gold particles were detected in all cellular nuclei, basement membranes, mast cell granules and collagen fibres, while the luminal surfaces of all vascular endothelial cells were devoid of gold label. Application of the method for detection of anionic domains under various conditions is discussed.
