the bromocresol(or bromocresol: BCG) green dye-binding method for plasma albumin appears to be suitable for most laboratory animal species unsuitable unlike some other albumin-binding dyes. Bromocresol purple appears to be unsuitable for most laboratory species depends on the regent constitution. proteins other than albumin such as alpha-1-globulins may react with bromocresol green if the absorbance measurements are made more than 60s after reagent
