Folin-Ciocalteu reagent : protein quantification :: Bradford assay : ?

Folin‑Ciocalteu reagent is used to determine how much phenolic compounds are in a sample. In the same way, the Bradford assay is a quick color‑change test that tells you how much protein is present. Both methods rely on a dye that shifts color when it binds to its target molecules. For example, adding Bradford dye to a protein solution turns it blue, and the deeper the blue, the more protein is there. Thus, the Bradford assay is to protein measurement what Folin‑Ciocalteu is to phenolics.
