产品描述

Application

Bromocresol Green sodium salt has been used as a pH indicator for glutamate decarboxylase activity assay in Listeria monocytogenes strains.[3]

包装

25 g in glass bottle

Biochem/physiol Actions

Bromocresol Green is mainly used for measuring serum albumin. In presence of acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630nm. The change in absorbance is linked with the concentration of albumin.[1] Bromocresol Green is also a pH indicator, changing from yellow (pH 4.0) to blue color (5.4).[2]
