The reversible binding of anti-human serum albumin to poly β-cyclodextrin-coated porous silica supports
چکیده انگلیسی

A supramolecular system involving host–guest interactions between immobilized β-cyclodextrin (β-CD) cavities and adamantyl groups was evaluated for the preparation of immunosorbents which can be regenerated after use. First a dextran layer bearing both adamantyl groups and carboxylic functions is immobilized onto β-CD-modified porous silica particles (400 nm) by formation of inclusion complexes. Then, antibody molecules are grafted to the polymer layer. The stationary phases can be prepared in batch or directly in the column. They are stable in aqueous media and are able to trap specifically the corresponding antigen. In case of alteration of the antibody layer, it is possible to remove it by passing a SDS solution through the column. The feasibility of the procedure was evaluated, using the anti-HSA/HSA system.
