WebThe Folin–Ciocalteau reagent is prepared by boiling a solution containing sodium tungstate, sodium molybdate, and phosphoric and hydrochloric acids, which produces … WebFolin & Ciocalteu′s phenol reagent is most commonly used in the Lowry method for determining protein concentration. [ 1] [ 2] It has also been used for the quantification of total phenolics. [ 3] In this method, protein is pretreated with copper (II) in a modified biuret reagent (alkaline copper solution stabilized with sodium potassium tartrate).

WebDec 2, 2024 · Folin-Lowry method Quick Reference A sensitive method of protein assay in which protein reacts both with an alkaline copper tartrate solution and with the Folin‐Ciocalteu reagent to give a blue colour, the absorbance of which is measured at 750 nm. Compare Lowry method. From: Folin‐Lowry method in
WebLowry’s assay for total protein is one of the most commonly performed colorimetric assays. This procedure is sensitive because it employs two colour forming reactions.
WebLowry adds phosphomolybdic/phosphotungstic acid also known as Folin-Ciocalteu reagent.
