Phenol Red sodium salt

Catalog No.: A44623
pH Indicator Dye
Phenol Red sodium salt is a pH indicator dye with a primary role as an acid-base indicator. It exhibits a distinct color change from pink to yellow in response to shifts in pH, allowing for effective monitoring in various biological assays. Additionally, Phenol Red sodium salt acts as an antagonist of rat P2X1R and enhances the halogenating activity of myeloperoxidase, making it valuable for studies involving cellular mechanisms and enzyme activities. Its applications extend to cell culture and biochemical research where precise pH measurement is essential.
