High-performance affinity chromatography of a chick lectin on an adsorbent based on hydrophilic polymer gel

A mouse monoclonal antibody (SIA4-5) which reacts with a chick 14K lectin (C14K) was covalently attached to a new support for high-performance affinity chromatography, TSKgel Tresyl-5PW, which is a preactivated, polymer-based particle. The immobilized antibody (SIA4-5-5PW) thus prepared proved to be useful in measuring not only the molecular properties of C14K but also specific interactions of C14K with SIA4-5 and hapten sugars. The C14K preparation was fractionated according to the oligomeric structure and with slight differences in affinity to SIA4-5 although the former was homogeneous in sodium dodecyl sulphate polyacrylamide gel electrophoresis. Application of the method for quantitative analytical purposes was successful.
