Folin-Ciocalteu's reagent for analysis of phenols

Supplier: SIGMA ALDRICH MICROSCOPY

Folin & Ciocalteu's phenol reagent is most commonly used in the Lowry method for determining protein concentration. It has also been used for the quantification of total phenolics. In this method, protein is pretreated with copper(II) in a modified biuret reagent (alkaline copper solution
stabilized with sodium potassium tartrate). Addition of the phenol reagent generates chromogens that give increasing absorbance between 550-750nm. Normally, absorbance at the peak (750 nm) or shoulder (660 nm) are used to quantitate protein concentrations between 1 - 100 mg/ml while absorbance at 550 nm is used to quantitate higher protein concentrations.
