Phenol red concentration
Did you know?
WebThe phenol red dye indicator is a weak organic acid, and its unionized acid and base forms are present in a concentration ratio that is determined by the ionization constant of the acid and the pH of the medium according to the familiar Henderson-Hasselbach equation. 3 The two forms of the dye have different optical absorption spectra.
WebPhenol red-free formulations are recommended for assays that require color detection. Phenol red may exhibit estrogenic effects, so we recommend using phenol red-free Matrigel matrix if estrogenic effects are an application concern. Phenol red containing formulations are manufactured with DMEM containing phenol red. WebPhenol red indicator changes from yellow to red over the pH range 6.8–8.4. Thymolphthalein (the alternative bromothymol blue could also be used) changes from blue (alkaline) to colourless (acid) over the pH range 9.3–10.5. ...
