Folin & Ciocalteu′s phenol reagent, 500ml

Folin & Ciocalteu′s phenol reagent has been used for the estimation of total phenolic content in samples. Addition of the phenol reagent generates chromogens that give increasing absorbance between 550-750nm. Normally, absorbance at the peak (750nm) or shoulder (660nm) are used to quantitate protein concentrations between 1-100 mg/ml while absorbance at 550nm is used to quantitate higher protein concentrations.
