General description

Phenol Red Sodium Salt (PRSS) is a water-soluble anionic fluorescent dye, that possesses an extra Na ion attached with the SO3 group compared to phenol red. It is intended for use 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.

Application

Suitable for use as a pH indicator.
The sodium salt of phenol red is used widely in culture media to identify changes from neutral to acidic pH values and as a pH marker for cell tissue culture. It is typically used in cell culture media at 11 mg/L. Phenol red in tissue culture media can act as a weak estrogen, especially in human breast cancer cells. PRSS plays a role as an indicator in the process of dying cells or overgrowth of cells in different mediums.
