Mucicarmine
Mucicarmine staining is intended for use in the histological visualisation of acid mucopolysacharides in tissue sections. Mucin is a secretion produced by a variety of epithelial cells and connective tissue. Mucicarmine is one of the oldest techniques for the detection of mucins. Although not as commonly used as it was, mucicarmine is still a valuable technique for the evaluation of acid mucins particularly those of the gastrointestinal tract. In addition, this technique is also useful for staining the capsule of the fungus Cryptococcus neoformans. The mucicarmine staining technique is also useful for determining the site of a primary tumor by visualizing tumor cells producing mucin in an area not containing mucin-producing cells.
