A monoclonal antibody to Bacillus anthracis protective antigen defines a neutralizing epitope in domain 1.
Antibody (Ab) responses to Bacillus anthracis toxins are protective, but relatively few protective monoclonal antibodies (MAbs) have been reported. Protective antigen (PA) is essential for the action of B. anthracis lethal toxin (LeTx) and edema toxin. In this study, we generated two MAbs to PA, MAbs 7.5G and 10F4. These MAbs did not compete for binding to PA, consistent with specificities for ...
متن کاملGenetic diversity in the protective antigen gene of Bacillus anthracis.
Bacillus anthracis is a gram-positive spore-forming bacterium that causes the disease anthrax. The anthrax toxin contains three components, including the protective antigen (PA), which binds to eucaryotic cell surface receptors and mediates the transport of toxins into the cell. In this study, the entire 2,294-nucleotide protective antigen gene (pag) was sequenced from 26 of the most diverse B....
متن کاملDuration of protection of rabbits after vaccination with Bacillus anthracis recombinant protective antigen vaccine.
Long-term protection of rabbits that had been vaccinated with two doses of a recombinant protective antigen (rPA) vaccine was examined against an aerosol spore challenge with the Ames isolate of Bacillus anthracis at 6 and 12 months. At 6 months after the primary injection, survival was 74.1% (20/27) with quantitative ELISA titer of 22.3 microg of anti-rPA IgG per millilitre and toxin neutraliz...
متن کاملCrystallization of the protective antigen protein of Bacillus anthracis.
The protective antigen protein, one of the three separate proteins constituting the exotoxin system of Bacillus anthracis, has been crystallized in a form suitable for structural studies. The crystal form which is most amenable to x-ray analysis is orthorhombic, space group P2(1)2(1)2(1), a = 101.1 A, b = 95.4 A, c = 87.3 A, with one protective antigen monomer/asymmetric unit. The crystals diff...
