General description
Pertussis (Pertussis) toxin (PTX) is a protein isolated from the bacterium Bordatella (Bordatella) coccobaccillus. The toxin is excreted in a non-active state. When the B oligomer of the bacterium, Bordatella coccobacillus, comes in contact with the cell membrane, an S1 subunit of its A protomer is activated. This activation may be mediated by glutathione and/or ATP.
Application
Inactive toxin form released from B. pertussis.
Pertussis toxin from Bordetella pertussis has been used: to enhance cardiac myosin immunization of rats to induce myocarditis[1]; to break down the blood–brain barrier in the Cuprizone and cuprizone/MOG-EAE model;[2] as an inhibitor of Gαi signaling[3]
The toxin is released from B. pertussis in an inactive form. When the pertussis toxin B oligomer binds to the cell membrane, the S1 subunit of its A protomer becomes activated, perhaps through the action of glutathione and ATP. A protocol for activating pertussis toxin in vitro is given by Kaslow, et al.
Biochem/physiol Actions
Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt.
Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt. This prevents the G protein heterotrimers from interacting with receptors, thus blocking their coupling and activation. Since the Gα subunits remain in their GDP-bound, inactive state, they are unable to inactivate adenylyl cyclase or open K+ channels.

G-protein receptor kinases (GRKs) regulate adult hearts by modulating inotropic, chronotropic and hypertrophic signaling of 7-transmembrane spanning neurohormone receptors. GRK-mediated desensitization and downregulation of β-adrenergic receptors has been implicated in adult heart failure; GRKs are therefore a promising therapeutic target.

We purchased the 50 uG size of the P2980 Pertussis Toxin. I am unable to find what the volume of solution in the container is to calculate uG/mL concentration.
