Related Product Information for Phenol Red Sodium Salt reagent
Phenol red is used as a pH indicator. A solution of phenol red exhibits a gradual transition from yellow to red over the pH range 6.8 to 8.2. Above pH 8.2, phenol red turns a bright pink (fuchsia) color. The sodium salt of phenol red is used widely in culture media to identify changes from neutral to acidic pH values. It is typically used in cell culture media at 11mg/L. Acid end products from carbohydrate fermentation lower the pH causing the pH indicator phenol red to turn from red (alkaline) to yellow (acid). Phenol red in tissue culture media can act as a weak estrogen, especially with human breast cancer cells. Lipophilic impurities, not the phenol red dye itself, account for the estrogenic activity. 95-99% of these impurities can be removed from the sodium salt of phenol red with a reduction in estrogen-like activity. P4040 appropriate for use in cell culture applications. Phenol red added as a component to tissue culture media can be autoclaved.

Product Notes
The Phenol Red Sodium Salt (Catalog #AAA635376) is a Reagent and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Phenol Red Sodium Salt, Reagent" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
