Brown powder | [Uses]
Cresol Red sodium salt acts as a constituent of polymerase chain reaction reagent systems. It is useful as a pH indicator with color changes with pH 0.2 - pH 1.8 and pH 7.1 - 8.8. Further, it plays an important role in molecular biology reactions in place of other loading dyes. | [Biological Activity]
Cresol Red is used as a pH indicator. |
