[Production and characterization of specific monoclonal antibody against Porphyromonas endodontalis]

Porphyromonas endodontalis was known to be important microorganisms in the etiology of pulp and apical infection. In this paper, we generated hybridomas secreting monoclonal antibody against Porphyromonas endodontalis ATCC 35406. The specificity of the monoclonal antibody was examined by ELISA against a battery organisms (109 Strains). The results indicated that the monoclonal antibody did not react with any non-Porphy romanas endodontalis (104 Strains). So our monoclonal antibody is specific for Porphyromanas endodontalis and can be used in clinical samples for detection of pulp and apical infections.
