Southgate’s Mucicarmine Stain Kit

Description Aluminum is believed to form a chelation complex with the carmine, changing the molecule to a positive charge allowing it to bind with the acid substrates of low density such as mucins. To stain mucin which is a secretion produced by a variety of epithelial cells and connective tissue cells. Excess mucin is secreted by epithelial cells in certain inflammations and in certain intestinal carcinomas. The mucicarmine technique is also useful in determining the site of a primary tumor in that finding mucin positive tumor cells in an area that does not contain mucin producing cells would indicate the tumor did not arise from that area. It is also useful in staining encapsulated fungi and cryptococcus.
