The reaction is similar to that described in the “Lowry Assay: Protein by Folin Reaction” by Lowry et al in the Journal of Biological Chemistry, 1951. The assay is based on the reaction of protein with an
WebThe Folin phenol reagent method consists of two steps. The first step is that under alkaline conditions, the protein reacts with copper to form a protein copper complex. The second step is that this complex will reduce Folin reagent to produce dark blue, and the color depth is proportional to the protein content. WebJan 30, 2024 · Principle: The principle involved in Lowry method is determining the protein concentration by calculating the reactivity of the peptide nitrogen with the Copper ions under alkaline conditions followed by reduction reaction of Folinciocalteay phosphomolybdic phophotungstic acid to Heteropolymolybdenum blue by copper What is the Folin Lowry …
