Description

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
