title: Postembedding immunogold labeling for electron microscopy using "LR White" resin.
abstract: A method is described for performing postembedding immunogold immunocytochemistry on sections of LR White-embedded tissues. Fixation of tissue in a combination of paraformaldehyde and glutaraldehyde, or with low concentrations of glutaraldehyde followed by partial dehydration, resulted in preservation of antigenicity for a variety of proteins in different tissue samples. Good structural preservation facilitated high-resolution immunolabeling when coupled with the use of purified monoclonal antibodies. The technique is straightforward and versatile, offering the potential for many immunocytochemical applications with minimal modifications.
