"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.
