Abstract
Disclosed is an improvement to the technique for immobilizing an analyte onto a solid surface for use in a competitive immunoassay. The improvement involves immobilizing the analyte on the solid surface by reacting the analyte or derivative thereof with polyethylene glycol which has been functionalized with a group which is reactive with the analyte contacting the resulting conjugate with the solid surface to thereby immobilize the analyte.
