What is line that bisects the light band in muscle? The alcian blue stain at a pH of 2.5 will stain for both sulfated (sulphomucins) and carboxylated (sialomucins) mucopolysaccharides which are found in the goblet cells located in the intestine. First dewax the tissue section and bring it down to the water for the hydration of the tissue section. Alcian blue is the most common stain used for demonstrating the presence of acidic mucins, since the blue dye molecules are cationic (positively charged) and bind to the Deparaffinization: flame the slide on burner and place in the xylene. Results Mucin pattern in adult predominantly secretes Presentation Transcript. This staining is performed to see the mucoid degeneration and to identify acid mucins which are released by various connective and epithelial tissue tumors. A reticulin stain occasionally helps to highlight the growth pattern of neoplasms. Standardized staining procedures for histology laboratory. Histology Buffers #1 in Diagnostic Reagents: Special Stains, Antibodies, Microbiology. Survey the two alternate slides to compare the relative proportions of mucous acini in these two glands. This is believed to be due to a low concentration of alum and high pH of the hematoxylin staining solution.
