Description

It is employed as an electrophoresis tracking dye and also finds its uses as an industrial dye, a laboratory acid-base indicator and a biological stain to detect proteins and nucleic acids (absorbance at 610 nm), particularly when staining living tissues. In gel electrophoresis it can be used as a color marker and as a biological stain it can be used to stain proteins and nucleic acids. Bromophenol blue is an intermediate and is used as an acid-based indicator in the pH range of 3-4.6 where the color changes from yellow to blue.

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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
