Basic Description Synonyms PHENOL RED|phenolsulfonphthalein|143-74-8|Fenolipuna|Sulfonphthal|Sulphental|Sulphonthal|Phenolsulphonphthalein|Phenolred|PSP (indicator)|Phenolsulfonephthalein|3,3-Bis(4-hydroxyphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide|Phenol, 4,4'-(1,1-dioxido-3H-2, Specifications & Purity 0.1%(w/v)in water Biochemical and Physiological Mechanisms pH indicator widely used in culture media to identify pH changes from neutral (red) to acidic (yellow) values. Typically a change in color from red to yellow indicates high rates of cellular death when used in tissue cultures. Shipped In Normal Note Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
