Bca assay wikipedia
WebJan 1, 2024 · The BCA assay is a biochemical, calorimetric (based on the measurement of colour) assay for the estimation of the total concentration of protein in a solution. Invented by Paul K. Smith of the Pierce Chemical Company in 1985, it is also called the Smith Assay. The assay determines protein concentration based on the colour change of the test ... WebBCA Assay Protein determination is one of the most common operations performed in biochemical research. The principle of the bicinchoninic acid (BCA) assay is similar to the Lowry procedure, in that both rely on the formation of a Cu 2+ -protein complex under alkaline conditions, followed by reduction of the Cu 2+ to Cu 1+.
