Phenol red sodium salt solution 0.5%, dark red solution
Supplier: MP Biomedicals
Phenol red is an acid-base indicator. It is made by condensing two moles of phenol with one mole of o-sulfobenzoic acid anhydride.
Phenol Red is used as a pH indicator in cell culture applications. A solution of phenol red will have a yellow color at a pH of 6.4 or below and a red color at a pH of 8.2 and above. Phenol red in tissue culture media can act as a weak estrogen, especially with human breast cancer cells. Phenol red can be used to measure hydrogen peroxide in cultured macrophages in multiwell plates.

Phenol red sodium salt
Supplier: Adipogen
Water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range and frequently used in cell biology laboratories. Widely used as cell tissue culture pH marker. A small amount of phenol red added to the growth medium will have a pink-red color under normal conditions. Typically, 15 mg/l are used for cell culture. In the event of problems, waste products produced by dying cells or overgrowth of contaminants will cause a change in pH, leading to a change in indicator color. For example, a culture of relatively slowly dividing mammalian cells can be quickly overgrown by bacterial contamination. This usually results in an acidification of the medium, turning it yellow. The waste products produced by the mammalian cells themselves will slowly decrease the pH, gradually turning the solution orange and then yellow. This color change is an indication that even in the absence of contamination, the medium needs to be replaced. Shown to be a weak estrogen mimic (possible through inpurities), which can enhance the growth of cells that express the estrogen receptor in cell cultures. Might be useful as a differentiation factor.
