Production of monoclonal antibodies against Clostridium difficile cytotoxin using immunosorbent binding bioassay procedure

Toxicon. 1993 Feb;31(2):181-6. doi: 10.1016/0041-0101(93)90284-p.

Abstract

In the following study, a novel screening approach was used to develop monoclonal antibodies specific for toxin B of Clostridium difficile. The approach, which consisted of an immunosorbent binding bioassay (ISBBA), is based on antigen immunocapture by monoclonal antibodies and detection of biological activity. Our results showed ISBBA, which uses unpurified antigen, to be more sensitive than the neutralization assay and ELISA for the detection of toxin B antibody.
