Mucin are high molecular weight glycoproteins that have gel forming properties, which contribute to protection against microorganisms, toxins in the gut lumen & also provide lubrication & mechanical protection from the intestinal content. Mucin secreted by different mucus secreting cells mainly found in the mucosa of the gastro intestinal tract by the goblet cells or modified epithelial cells. Mucins are glycoproteins and their carbohydrate component is deeply stained with PAS for demonstrating mucous secreting cell in comparison to routine staining with H&E which gives vacuolated appearance to the cytoplasm of mucous secreting cells.
The present study does not aim to classify or comment on the nature of the classification, an attempt to explore the mucins and its special affinity to react with Schiff reagent is documented in the present study.
