NR-31826, Bordetella pertussis Toxin, Salt-free, is no longer available.

NR-31826 was isolated from the supernatant of a culture of Bordetella pertussis (B. pertussis) by a modification of the method of Cowell et al. The purified protein consists of five dissimilar subunits migrating as distinct bands on SDS-PAGE gels: S-1 (molecular weight 28000 da), S-2 (23000 da), S-3 (22000 da), S-4 (11700 da), and S-5 (9300 da). S-1 is the A promoter (responsible for the enzymatic activity of the toxin), and S-2 to S-5 comprise the B oligomer (responsible for the binding of the toxin to the cell surface). NR-31826 contains no detectable fimbrial hemagglutinin on gels. The level of contaminating adenylate cyclase activity is shown on the Certificate of Analysis.

Each vial contains approximately 50 µg (lyophilized) of Pertussis toxin.
