Trypanblau 0,4% in PBS, dunkelblaue Lösung
Lieferant: ICN Biomedicals
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.
- Suitable for cell culture
- Presentation: Dark Blue Solution
- Potassium Phosphate Dibasic: 600.00000 mg/L, Sodium Chloride [NaCl]: 8100.00000 mg/L, Trypan Blue: 4000.00000 mg/L
- Soluble in ethylene glycol monomethyl ether (methyl cellosolve; EGME) (20 mg/mL); Slightly soluble in water or ethanol (0.6 mg/mL); almost insoluble in alcohol.
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.
