Product Image-97063-702

Trypan blue 0.4% in aqueous solution ready-to-use, sterile

Catalog Number: (97063-702)
Supplier: VWR
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.

Product Image-76180-676

Trypan blue 0.4% in PBS, dark blue solution

Catalog Number: (76180-676)
Supplier: MP Biomedicals
Description: Trypan Blue is a blue acid dye with a strong affinity for cellulose containing substrates such as cotton; less affinity for proteinaceous materials. Trypan blue solution may be used in trypan blue based cytotoxicity and proliferation assays.
Trypan Blue is used as a vital dye which is especially important because it is taken up by the reticuloendothelial system. Clark describes assays for the study of teratogenic action of trypan blue on embryonic tissues using Davis and Sauter's fluorescence method and for the staining of collagen, including very fine fibrils, muscle and cornified epithelium using the Van Gieson method. Trypan blue is also recommended for use in dye exclusion procedures for viable cell counting. Non-viable cells will up-take trypan blue at a faster rate than viable cells.
