Trypan blue is a tetrasulfonated anionic, hydrophilic azo dye derived from toluidine. The non-permeable cell membrane dye is a vital dye that selectively stains dead or non-viable cells, that pass through damaged but not through intact cell membranes.
- it is a routinely used for viability testing for diverse cell types including frozen sperm and aortic muscle cells exposed to antifungal agents
- employed as a collagen stain in a Van Gieson procedure
- To stain amyloid, Trypan blue is considered as a blue alternative to Congo red in Puchtler-Bennhold stains
- used as a fluorescent tracer of cell populations in embryology
- used as a tumor promoter modulating permeability of lysosomal membranes
Physical form: 0,4% in 0,81% sodium chloride; 0,06% potassium phosphate, dibasic.
