英文摘要To replace conventional affinity ligand like protein A or protein G, a pseudobioaffinity ligand seems to be an alternative for the purification of immunoglobulin G (IgG). In this study, sulfamethazine (SMZ) was chosen as novel affinity ligand for investigating its affinity to human IgG. Monodisperse, non-porous, cross-linked poly (glycidyl methacrylate) (PGMA) beads were employed as the support for high-performance affinity chromatography. SMZ was immobilized on PGMA beads using bisoxirane (ethanediol diglycigyl ether) as spacer. The resultant affinity media presented minimal non-specific interaction with other proteins. Results of high-performance frontal analysis indicated that the media showed specific affinity to human IgG with a dissociation constant on the order of 10(-6) M. The SMZ affinity column proved useful for a very convenient one-step purification of IgG from human plasma. Antibody purity after a one-step purification was higher than 90%, as determined by densitometric scanninng of sodium dodecyl sulfate-polyacrylamide gel electrophoresis of purified fraction under reducing condition. The results obtained indicate that SMZ is a valuable affinity ligand for purification of human IgG. (C) 2003 Elsevier B.V. All rights reserved.
