Anti-Pertussis Toxin antibody, rabbit serum

Anti-Pertussis Toxin Antibody, Rabbit Serum. Pertussis toxin (PT) is a protein-based AB5-type exotoxin produced by Bordetella 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 molecule of each S1 (26 kDa), S2 (22 kDa), S3 (22 kDa), S5 (12 kDa) and two molecules of S4 (12 kDa). This antibody is 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.
