Sodium bicinchoninate

4,4 EDicarboxy-2,2 Ebiquinoline, disodium salt. Ap Application: Cu(I) determination, colorimetric.


Sodium bicinchoninate is a Cu(I)- specific colorimetric reagent that is more sensitive than neocuproine. Its absorption maximum is at 562 nm (molar absorptivity: 7,900). In alkaline solution, Cu(II) is reduced by proteins to Cu(I), and then forms a purple complex with Sodium bicinchoninate. The protein detection range of this assay is 1-2,000 mg per ml.
