摘要
Growth hormone [GH] and prolactin [PRL] were localized on thin plastic sections of rat anterior pituitary gland and mammosomatotropic tumor MtTW15 that were fixed with osmium tetroxide (alone, mixed with aldehydes, or after aldehydes). Intense immunocytochemical staining for both antigens was obtained after plastic was removed from sections with an alcoholic solution of NaOH. Antigenic determinants of rat PRL and GH were not completely destroyed or inactivated by fixation with osmium and embedment in epoxy resin and removal of the polymerized epoxy resin was necessary to obtain light microscopic postembedding immunocytochemical staining of these antigens. Tissues which have been conventionally processed for morphological evaluation by EM may be suitable for postembedding immunocytochemical staining of some antigens for light microscopy.
