UV Spectral Study on the Interaction of RE Ions with BSA

Laboratory of Rare Earth Chemistry and Physics, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022

Revised Date: 11 September 1997

The interaction of RE ions(Ⅲ) with bovine serum albumin(BSA) has been stud-ied by UV spectrometry. It was found that the absorption of BSA at near 280 nm was en-hanced by RE ions. Ultraviolet spectra showed that the coordination atoms of BSA to RE ions are oxygen atoms, RE ions were coordinated with carboxyl groups of amino acids and carbonyl groups of the peptide bonds on the out-shell of BSA.
