Description and Uses

2,2’-Biquinoline-4,4’-dicarboxylic acid (BCA) is a colorimetric reagent for the detection of copper (Cu⁺). BCA and Cu⁺ form a stable 2:1 complex that has an absorbance maximum at 562 nm. It is commonly used as a reagent in the colorimetric BCA protein quantitation assay in which Cu²⁺ is converted to Cu⁺ as a function of protein concentration under alkaline conditions.

For determination of Cu and protein assays.Bicinchoninic acid disodium salt is useful for the determination of copper. It is also used for the determination of protein concentration.
