title: Determination of a monoclonal antibody binding activity using immunodetection.
abstract: A method for measuring the binding of chimeric IgG BR-96 to the Lewis Y antigen using the ImmunoDetection technology has been developed. The procedure is rapid (2 min), highly reproducible (< 5% CV), and has excellent correlation with the Lewis Y and anti-idiotypic enzyme immunoassays. Samples that were degraded by heat or by repeated freeze-thaw cycles showed reduced binding activity. There was minimal cross-reactivity with other proteins typically found in hybridoma media or with another chimeric IgG directed against a different antigen (L6). The fact that this assay can be performed using conventional HPLC equipment makes it especially attractive because it can be completely automated using equipment readily available.
