This product was highly purified (>90 % pure) from Bordetella pertussis strain Tohama by the method of Skelton & Wong. Cytotoxicity of the PT was confirmed by morphological alteration of CHO cells after treatment with 0.1 ng/mL of PT.

Skelton, Wong: "Simple, efficient purification of filamentous hemagglutinin and pertussis toxin from Bordetella pertussis by hydrophobic and affinity interaction." in: Journal of clinical microbiology, Vol. 28, Issue 5, pp. 1062-5, (1990) (PubMed).
Perrtussis toxin (PT) is a protein-based AB5-type exotoxin produced by Bordeterra pertussis. PT catalyzes the ADP-ribosylation of the alpha subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt and prevents intracellular signal transduction involving the G proteins. PT consists of one moplecule of each S1 (26 kDa), S2 (22 kDa), S3 (22 kDa), S5 (12 kDa) and two molecule of S4 (12 kDa).
