Technical Note: Colorimetric Protein Assays

WebThe Biuret assay is the first method, which involves the coordination of a metal ion with successive nitrogen atoms in the polypeptide backbone to produce a deep violet color. This method is less sensitive than other well-known assays and is susceptible to interference from commonly used compounds. WebProtein estimation is used in every lab involved with proteins, but which assay is the best choice. Here's an overview of the Lowry Protein Assay, Bradford Protein Assay, BCA Protein Assay, assaying by UV absorption and the Biuret Protein Assay. The review focuses on sensitivity, specificity and time! WebJan 1, 2024 · The BCA Assay is actually a two step reaction. 1) The first step is the biuret’s reaction. Here, Cupric ions (Cu++) from cupric sulphate (or any other source of cupric) are reduced to cuprous ions (Cu+) by the amino groups on the backbone of protein chains. 2) The second step is where the BCA – bicinchoninic acid (image) comes to play. fishers grocery raleigh nc
