The effect of binding hydrophilic materials on amount of ligand bound-Cibacron Blue F3GA (CBF) was investigated. Experimental data showed that the amount of CBF bound can be increased significantly after binding of hydrophilic materials.展开更多

The affinity membrane obtained can be used to adsorb γ-globulin specifically. The optimum conditions of preparing affinity membrane and adsorbing bovine γ-globulin were studied.展开更多
