How does a bca assay work
WebThe BCA protein assay is used to quantify total protein in a biological sample. BCA stands for Bicinchoninic acid, which is the key reagent used to produce a colored product. The … WebThe Bradford protein assay is based on the observation that the absorbance maximum for an acidic solution of Coomassie Brilliant Blue G-250 shifts from 465 to 595 nm when binding to protein occurs. The extinction coefficient of a dye-albumin complex solution is constant over a 10-fold concentration range.

Firstly, the peptide bonds in the protein sample reduce Cu2+ ions, in a temperature dependent reaction, from the copper solution to Cu+. The amount of Cu2+ reduced is proportional to the amount of protein present in the solution.
A stock BCA solution contains the following ingredients in a highly alkaline solution with a pH 11.25: bicinchoninic acid, sodium carbonate, sodium bicarbonate, sodium tartrate, and copper(II) sulfate pentahydrate. The BCA assay primarily relies on two reactions. First, the peptide bonds in protein reduce Cu ions from the copper(II) sulfate to Cu (a temperature dependent reaction). The amount of Cu reduce…
