Bicinchoninic Acid CAS:1245-13-2

Bicinchoninic acid CAS:1245-13-2 is a weak acid composed of two carboxylated quinoline rings. Bicinchoninic acid is most commonly employed by biochemists in the bicinchoninic acid (BCA) assay, which is used to determine the total level of protein in a solution. In this assay, two molecules of bicinchoninic acid chelate a single Cu+ ion, forming a purple water-soluble complex that strongly absorbs light at 562 nm.  Bicinchoninic acid CAS:1245-13-2 is light brown solid, raw material of bicinchoninic acid disodium salt CAS:979-88-4, which is BCA assay reagent. Bicinchoninic acid CAS:1245-13-2 could be supplied in commercial size with competitive price.
