VWR Life Science AMRESCO BCS Assay Kit

Supplier: VWR

  • Reduced variability from protein to protein sample
  • High tolerance for salts, detergents and buffers
  • Reproducible and Consistent Results
The BCS Assay is a kit that allows for spectrophotometric determination of protein concentration. The BCS Assay utilizes a biuret-like reaction where Copper (II) binds protein. The remaining free Copper (II) then is reduced to Copper (I) which associates with a dye that changes colors upon binding of copper (I). Protein concentration is then determined by measuring the absorbance of the dye-Copper (I) complex. The signal is inversely proportional to the concentration of peptide bonds as opposed to specific amino acid side chains. Therefore, protein to protein variability is less of a concern. Another advantage of the BCS Assay is that the BCS assay has a high tolerance for salts, detergents, and buffers that may interfere with conventional protein quantitation kits.
