General description

Trypan Blue (C.l. 23850) is a large, tetrasulfonated anionic, hydrophilic dye. It is also known as diamine blue 3B.

Application

Trypan blue has been used as a dye in trypan blue exclusion assay/cell viability assay to detect dead cells.

Biochem/physiol Actions

Trypan Blue is excluded by most living cells, but can be taken into phagocytes and certain other cells.

This dye is useful to differentiate the dead and live cells based on the cell′s ability to take up or exclude the dye. A viable cell is assumed to possess an intact cell membrane and hence excludes this dye and the cytoplasm appears clear. While on the other hand non-viable cells shows a blue cytoplasm.
Trypan blue is routinely used for viability testing for diverse cell types including frozen sperm and aortic muscle cells exposed to antifungal agents. It is also 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. It is suitable for use in cell viability assay:
  • to determine the number of living and necrotic cells by staining with 0.2% trypan blue solution.
  • to stain plant tissue in order to visualize cell death.
