ABSTRACT
A new nylon affinity matrix with L-tryptoph ane as ligand was prepared for adsorption of bovine γ-globulin. Effects of tem perature, ionic strength and pH on affinity adsorption of γ-globulin on affinity membrane were studied by batch method. The results show that the interaction between ligand and γ-globulin includes mainly electrostatic and hydrophobic interaction. The affinity adsorption at optimum condition obeys Langmuir adsorption model with maximum adsorption capacity and minimum nonspecific adsorption. The space location between protein and ligand and the configuration of proteins wi ll change when deviating from this condition.
