title: An improved dot immunobinding assay for screening hybridoma supernatants. Non-purified antigen immobilized on nitrocellulose paper discs.
abstract: This report describes a modified dot immunobinding assay (DIA) in microplates using a crude mixture of non-purified antigen. Nitrocellulose filter paper discs exposed to the antigen mixture were inserted into the wells and kept in place by a specially constructed device. To test the efficiency of the modification a set of monoclonal antibodies from a mouse immunized with 58 kDa trpE-Bmyc fusion protein were screened. The advantage of this modified method over conventional ELISA is that it permits the use of non-purified antigen for screening large numbers of monoclonal antibodies.
