| Hazard Information | Back Directory | [Description]
2,2’-Biquinoline-4,4’-dicarboxylic acid (BCA) is a colorimetric reagent for the detection of copper (Cu+).1,2 BCA and Cu+ form a stable 2:1 complex that has an absorbance maximum at 562 nm.1 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.1,3 | [Chemical Properties]
White to light yellow powder | [Uses]
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. | [Application]
2,2'-Bicinchoninic Acid Disodium Salt is a photometric reagent for protein assay. It is used for determination of reducing sugar and protein via Cu(I). Also a specific reagent for Cu(I) with sensitivity similar to that of neocuproin. | [Biochem/physiol Actions]
Bicinchoninic acid is used for the determination of protein concentration. It is responsible for the making of intense purple complex with cuprous ion (Cu+), in presence of alkaline conditions. The amount of Cu+ is in relation with the protein concentration. | [References]
