Bicinchoninic Acid Disodium Salt

Description

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.

Chemical properties

White to light yellow powder.
IUPAC Name is disodium [2,2'-biquinoline]-4,4'-dicarboxylate

The Uses of Bicinchoninic Acid Disodium Salt

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.
