Selection of monoclonal antibodies for immunoaffinity chromatography: model studies with antibodies against soy bean trypsin inhibitor.

To facilitate selection of monoclonal antibodies for immunoaffinity chromatography, an ELISA screening procedure was developed. The assay is based on the avidin-biotin system and provides a profile of the monoclonal antibody which is based on the binding characteristics of the antigen binding site when exposed to different elution reagents. The elution profiles of 5 monoclonal antibodies to soy bean trypsin inhibitor (SBTI) were determined and for 2 of the antibodies the results obtained in the ELISA were verified using column experiments. The affinity constants were determined for the same 5 monoclonal antibodies and no correlation was seen with the ease of elution. The elution profiles presented here are easily obtained and the results indicate that a general screening procedure for suitable combinations of antibodies and elution conditions can be carried out using an elution ELISA assay when modified as described herein.
