Folin's reagent
WebFolin & Ciocalteu’s phenol reagent suitable for determination of total protein by Lowry method, 2 N. It has also been used for the quantification of total phenolics. Webabsorption depends on the concentration of phenolic compounds. The reduced Folin-Ciocalteu reagent is detectable with a spectrophotometer in the range of 690 to 710 nm. The reaction temperature has been used to reduce the time necessary to attain the maximum color (T= 37°C). Generally, gallic acid is used as the reference standard
