Web1. During the determination, special care should be taken when adding Folin phenol reagent, because the reagent is stable only under the acidic pH condition, but the reduction reaction only occurs when pH=10, so when Folin phenol reagent is added to the alkaline copper protein solution, it must be immediately mixed, so that the reduction reaction can … The Folin–Ciocâlteu reagent (FCR) or Folin's phenol reagent or Folin–Denis reagent, is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants, also called the gallic acid equivalence method (GAE). It is named after Otto Folin, Vintilă Ciocâlteu, and Willey Glover Denis.
