Key features and details | |
Cat. No. | MABL-1602 |
Name | Anti-FimA mAbs |
Clone No. | AFD- 256-265-9 |
From | Recombinant Antibody |
Isotype | Engineer antibody |
Application | inhibition, WB, ELISA |
Species Reactivity | Porphyromonas gingivalis |
Basic Information | |
Specificity | The antibody reacts with conformational epitopes displayed by partially dissociated oligomers of FimA, but not with the 43 kDa FimA monomer. FimA is a structural protein of P. gingivalis fimbriae and is known to be involved in bacterial adherence to the host cell surface. |
Alternative Name | Major fimbrium subunit FimA type-1; Fimbrillin; Major fimbrial subunit protein type I; fimbrial protein; fimbriae protein |
UniProt | B2RH54 |
Immunogen | The original antibody was generated by immunizing BALB/c mice with FimA protein. |
Application Notes | The antibody reacted with conformational epitopes expressed by partially dissociated oligomers, but not with monomer as elucidated by Western blot analysis. Ascites fluid containing the antibody showed the inhibitory activity against P. gingivalis to saliva-coated hydroxyapatite beads, an in vitro model for the pellicle-coated tooth surface. For example, 400-fold diluted monoclonal antibody inhibited the binding of the bacteria onto bead surfaces of 41.5%,(Koh et al., 2009; PMID: 20157608). The specificity of this antibody (IgG1) was confirmed by ELISA analysis. The original antibody detected FimA by western blot. The antibody significantly inhibited the binding of P. gingivalis to the surface of SHA beads by 51.81 ± 2.17%, when 50 ng/mL antibody was used (P 0.01). The antibody could be used as a basis for passive immunization against P. gingivalis-mediated periodontitis (Koh et al., 2011; PMID: 21223367). |
