Identification of the major surface protein antigens of Porphyromonas gingivalis using IgG antibody reactivity of periodontal case-control serum.

Abstract

The identity of the major surface antigens of Porphyromonas gingivalis was investigated. Outer membranes of P. gingivalis strains W83, W50, 381 and NCTC 11843 were prepared following inactivation of the trypsin-like enzyme activity. Three proteins, molecular weight 115, 55 and 40 kDa, were major components of the outer membranes of strains W83 and W50 and… (More)
