title: The detection of Clostridium perfringens epsilon antitoxin in rabbit serum by monoclonal antibody based competition ELISA.
abstract: A competitive enzyme-linked immunosorbent assay (CELISA) has been developed, standardized and compared with the toxin neutralization (TN) test performed in mice for the measurement of antibody responses in rabbits vaccinated with clostridial vaccines. In CELISA, sera were tested at a single dilution for their ability to compete with the reaction between a monoclonal antibody, which neutralizes epsilon toxin, and epsilon toxoid coated on to a solid phase. The results of the two tests correlated well. CELISA was specific, rapid, reproducible and simple to perform and offered an alternative to the TN test that reduced the requirement for experimental animals in the potency testing of clostridial vaccines.
