Grid-immunoblotting is a procedure that allows the simultaneous testing of up to 20 different antibodies such as monoclonal antibody-containing hybridoma supernatants or human sera for specific antibodies to up to 20 different antigens or allergens on a single sheet of nitrocellulose membrane. Since only 150 to 200 microl of antibody-containing solution are required this technique is uniquely suited to test growing hybridomas and small amounts of sera (e.g. mouse and children's sera). Compared to a standard ELISA, approximately ten times less antibody is needed to obtain the same information.
