摘要	The interaction of lanthanide(Ln(3+)) ions with trichosanthin(TCS) was investigated using Tb3+ as fluorescent probe. The metal-binding sites of the protein were probed by means of adding the Tb3+ into the protein solutions. If other Ln(3+) ions exist in the Tb3+-protein complex system, they would compete against Tb3+ in the binding sites of the protein, and so the fluorescence intensity of Tb3+ decreased, which is called quenching effect. The quenching effect is related to the ionic radii of the Ln(3+) ions and energy transfer from Tb3+-protein to Ln(3+) ions. Based on the experimental results, a schematic of the energy transfer from protein-Tb3+ complex to protein-Ln(3+) complex is suggested.
