Figure 2

Double immunodiffusion analysis of autoclaved supernatants of P. gingivalis strains. Samples of W83, the epsC mutant and the complemented mutant were tested against the K1-specific antiserum (central well). Note that the white precipitate indicating recognition of CPS with the antiserum is absent in case of the epsC mutant, whereas the intact epsC copy restores the wild-type K1 antiserum recognition in the complemented mutant.
