WebHow does the BCA assay work? The Bicinchoninic Acid (BCA) Protein Assay primarily relies on two reactions. 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. Webdifferent proteins in different ways. One may assay the protein of interest in deionized water alone, then in the buffer with possible interfering substances. Comparison of the readings will indicate if an interference exists. Note: Reagents that chelate metal ions, change the pH of the assay, or reduce copper will interfere with the BCA assay.
WebThe Bradford is recommended for general use, especially for determining protein content of cell fractions and assesing protein concentrations for gel electrophoresis.
