Abstract:

A macroporous boronate affinity monolithic column was prepared and applied to specifically capture glycoproteins using metal-organic gels (MOGs) as a porogenic template. This newly explored application of MOGs has proven to be a more convenient method for the formation of macropores in contrast to traditional porogenic methods. The poly (3-acrylamidophenylboronic acid-co-ethylene dimethacrylate) monolithic columns were synthesized in stainless columns by in situ polymerization. To fabricate the macroporous formation with a uniformed open-channel network, the preparation conditions, such as reaction temperature, the concentration of the MOGs and the ratio of monomers were systematically investigated. The prepared macroporous monoliths were characterized by scanning electron microscope (SEM) and mercury intrusion porosimetry. Furthermore, horseradish peroxidase (HRP) and transferrin (TF) were chosen as test glycoproteins, and the chromatographic analysis demonstrated that the macroporous boronate affinity monoliths exhibited a higher selectivity and better dynamic binding capacity toward glycoproteins compared with non-glycoproteins. The resulted affinity monolithic column was successfully employed to specifically capture TF from a bovine serum sample. © 2011 Elsevier B.V.
