Rhesus monkey, Helly's fluid, periodic acid-Schiff* stain, 612 x.
The method used in this preparation stains protein polysaccharicles (mucin) that are synthesized and excreted by goblet cells. The striated border and goblet cells are very well outlined, whereas the absorptive columnar epithelium and the lamina propria are not as intensely stained. The relatively unstained basal portion of the goblet cell represents the nuclear region and its surrounding narrow stem of cytoplasm.
*Schiff, 1834-1915, was a German chemist working in Florence, Italy.
