Bromocresol Blue

Bromocresol purple binds quantitatively with human serum albumin forming a stable complex with absorbance maximum at 600 nm. The intensity of the color produced is directly proportional to the albumin concentration in the sample. Bromocresol Purple is used as a pH indicator (5.2-6.8 : yellow to…
