Phenol Red sodium salt

Chemical properties

red liquid or red/brown crystals, slightly soluble in water, alcohol and acetone. Almost insoluble in ether and chloroform, soluble in hydroxide base or carbonate base solution with deep red color, stable in air, used as acid-base indicator.

The Uses of Phenol Red sodium salt

Phenol Red Sodium Salt is a water soluble pH indicator commonly employed in cell biology laboratories as a cell tissue culture pH marker. Phenol Red sodium salt is a water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range. It is commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. Usually 15 mg/l is used to produce this effect. If problems arise, such as dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, Phenol Red could potentially be useful as a differentiation factor. It can also be used as reactant/reag

The Uses of Phenol Red sodium salt

Phenol Red sodium salt has been used as an indicator during single-guide RNA microinjection into one-cell stage zebrafish embryos.

The Uses of Phenol Red sodium salt

Phenol Red has been used for preparation of phosphate buffer saline (PBS)-with phenol red for microfluidic assay for simultaneous culture of multiple cell types. It has also been used for horseradish peroxidase-phenol red (HRP-PR) H₂O₂ (hydrogen peroxide) detection assay to identify redox cycling compounds.

General Description

Phenol Red sodium salt is widely used as a pH indicator. At a pH of 6.4 and below, phenol red solution will have a yellow color. At a pH of 8.2 and above, it will have a red color. It is commonly used in culture media to detect neutral to acidic pH changes.

Biochem/physiol Actions

Phenol Red is a pH indicator which changes color from yellow to red.
