A new method of preparing gold probes for multiple-labeling cytochemistry.

Abstract

A new method is described for preparing colloidal gold particles in any size between approximately 3 and 17 nm for electron microscopy. The gold particles are homogeneous in size (homodisperse). When bound to various proteins (e.g. IgG and protein A), the complexes were stable for long periods and suitable for affinity cytochemistry. We demonstrated the usefulness of the new gold probes bound to protein A for multiple labeling in a current immunocytochemical study on receptor mediated transport of IgA in human duodenal crypt cells. Other gold-protein complexes were useful for studying macromolecular arrangements at high resolution.
