Here we take a model protein(bovine serum albumin) and a typical fluorophore(rhodamine B) to demonstrate a direct labeling method just by physical adsorption. In combination with size exclusion chromatography and the Scartchard equation, we have developed a facile analysis method for calculating the binding constant and binding sites.The molecular docking method has been used to study the binding site in amino acid level.展开更多
