荧光增白剂28二钠盐溶液，Fluorescent Brightener 28 disodium salt solution；used as a stain and brightening agent

Fluorescent Brightener (Calcofluor White M2R) is used for the staining of fungi and as a viability stain. Industrial uses include use as a fluorescent brightening agent for cellulose and polyamide fabrics, paper and in detergents and soaps.Fluorescent Brightener 28 has been used for the staining of fungal cell walls. It has also been used for the staining of Candida albicans biofilm.

 

Fluorescent Brightener 28 has been used in the identification and study of the structure and biosynthesis of chitin, the second most abundant polysaccharide found in nature, from the freshwater sponge Spongilla lacustris. Fluorescent Brightener 28, which shows enhanced fluorescence when binding to chitin, was used to elucidate particular location of chitin in the skeletal structures.
