[The determination of the antigenic determinant of protective monoclonal antibodies specific to the Francisella tularensis lipopolysaccharide]
Abstract
F. tularensis lipopolysaccharide (LPS) was studied with the use of monoclonal antibodies (McAb) having protective properties. The binding site of these McAb (IgG2a) is localized on the O-chain of LPS. In contrast to LPS isolated from vaccine strain 15, LPS isolated from F. tularensis cells in the R-form has no O-chains and does not interact with McAb.
