Here we describe a method for gross staining of gray matter in slices of formaldehyde-fixed human brain. After protection of white matter with 4% phenol at 60°C for 5 min followed by a cold water wash, the gray matter was stained for 10-15 min at 20-25°C with 1% aqueous copper(II) phthalocyanine tetrasulfonic acid tetrasodium salt (CPTS). The staining resisted all attempts to be washed from the gray matter. Stained slices can be stored indefinitely in slightly acidified water, or plastinated as permanent dry specimens. 相似文献

A simple and rapid method is described for staining semithin sections of material embedded in epoxy resin for observing tissues prior to transmission electron microscopy. The method is suitable for tissue fixed with a glutaraldehyde-formaldehyde mixture and postfixed in osmium tetroxide. No etching or oxidizing procedures are necessary. Sections 0.5-0.8 µm thick are dried onto a slide and stained with either 0.75% methylene blue and 0.25% azure B or 0.5% methylene blue and 0.5% azure II in 0.5% aqueous borax and heated over a flame for 8-10 sec. The slides are rinsed with water, then stained the same way with 0.1% basic fuchsine in 5% aqueous ethanol. Cytoplasm stains blue; nuclei darker blue; collagen, mucus and elastin pink to red; fat and intracellular lipid droplets gray-green. 相似文献

Summary A double staining method has been developed for light microscopic immunohistochemistry. The technique consists of a sequence of protein A-gold-silver procedures, in which the reaction products are visualized in black and brown colours. The results obtained in the rat pancreatic islets and adenohyophysis, in combination with a variety of histochemical controls, substantiate both the specificity and reliability of this method. The double staining method is simple and economical, since the two differently coloured reaction products are obtained by a common mechanism of colouration (physical development) using a single probe, protein A-gold. 相似文献
