Beschreibung

m-Cresol purple sodium salt is used to detect changes in pH during titrations at which color changes occur at pH 7.6-9.2. Upon bromination, m-cresol purple sodium salt creates the dye bromocresol green (sc-206036) which is used as a tracking dye in DNA agarose gel electrophoresis. In addition, m-cresol purple sodium salt can be used to stain epithelial cells and proteins. 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.
