SUMMARY: A monoclonal antibody (mAb), designated 15D8, was produced from BALB/c splenocytes of mice injected with flagella. ELISA of motile cells, non-motile cells and partially purified flagellin proteins showed that the mAb reacted specifically with flagella of and with other members of the family Enterobacteriaceae. Western immunoblot analyses of enterobacterial flagella or cell extracts demonstrated that the antibody reacted with a single protein species in the extracts which was identical in size to purified flagellin. The antigenic determinant for this antibody appears to be surface exposed and linear in configuration, since the antibody reacted with native flagella and flagella which had been denatured. This antibody was also used to demonstrate that although the flagella proteins are heterogeneous in size, at least one epitope is highly conserved.
