  • Bicinchoninic Acid Assay - an overview | ScienceDirect Topics
    Like all other colorimetric methods, this method is destructive to proteins Therefore, once the protein sample has reacted with the copper, the protein cannot be used for other assays
  • Bicinchoninic acid assay - Wikipedia
    The BCA assay primarily relies on two reactions First, the peptide bonds in protein reduce Cu 2+ ions from the copper (II) sulfate to Cu 1+ (a temperature dependent reaction) The amount of Cu 2+ reduced is proportional to the amount of protein present in the solution
  • How Does the BCA Protein Assay Work? - Biology Insights
    The purple color generated by the BCA-copper complex must be translated into a numerical value to determine the protein concentration of the unknown sample This measurement is achieved using a laboratory instrument called a spectrophotometer
  • Total Protein Determination with Bicinchoninic Acid (BCA method)
    This method combines the well-known reduction of Cu +2 to Cu +1 by protein in an alkaline medium (the biuret reaction) with the highly sensitive and selective colorimetric detection of the cuprous cation (Cu +1) using a unique reagent containing bicinchoninic acid
  • Chemistry of Protein Assays - Thermo Fisher Scientific - US
    The BCA Protein Assay combines the protein-induced biuret reaction (see above) with the highly sensitive and selective colorimetric detection of the resulting cuprous cation (Cu1+) by bicinchoninic acid (BCA)
  • Determination of Protein by Bicinchoninic Acid Assay
    The quantification of proteins is an important field in bioanalytic There are different methods of protein estimation in samples One method is the BCA protein assay, which is based on the reduction of Cu 2+ to Cu + by proteins Cu + then reacts with BCA to form a purple-blue complex
  • Protocol for Bicinchoninic Acid (BCA) Protein Assay
    The Bicinchoninic Acid (BCA) protein assay is a widely used method for the quantification of total protein in a sample The BCA assay relies on the reduction of Cu 2+ ions to Cu 1+ ions by protein in an alkaline medium
  • The Principle of the BCA Assay – The Heart of the Helix
    The BCA assay is a biochemical, calorimetric (based on the measurement of colour) assay for the estimation of the total concentration of protein in a solution Invented by Paul K Smith of the Pierce Chemical Company in 1985, it is also called the Smith Assay
  • BCA Protein Assay Kit | 71285 - Merck
    Bicinchoninic acid is a chromogenic reagent that chelates the reduced copper, producing a purple complex with strong absorbance at 562 nm (Smith 1985, Wiechelman 1988) This assay can be used to quantify protein concentration with a wide variety of samples and can be performed in minutes
