Description: Trypan Blue (C.l. 23850) is a large, tetrasulfonated anionic, hydrophilic dye. It is also known as diamine blue 3B. Trypan blue has been used as a dye in trypan blue exclusion assay/cell viability assay to detect dead cells.

Trypan blue 4 g/l in aqueous solution cell culture reagent

Catalog Number: (K940-100ML)

Supplier: VWR Chemicals

Description: A pre-mixed dye solution used in cell culture applications to determine cell viability. A researcher can remove a sample of cells from culture and combine in a 1:1 ratio with the Trypan Blue solution. Under the microscope, dead cells will appear a blue color and viable cells will appear clear and translucent. Using a hemacytometer (gridded microscope slide), a researcher can quantify the percentage of dead cells within a population. Stained cells are ready for counting within five minutes.
