Interaction of Tannin with Bovine Serum Albumin by Fluorescence   Spectrometry
  Interaction between tannin and bovine serum albumin (BSA) was examined by the fluorescent quenching. The process of elimination between BSA and tannin was the one of a stationary state, and the coupling coefficient was one. The working strength between the tannin and the beef serum was hydrophobic one.
