One unit increases adenylate cyclase activity 6-fold, measured as [3H]-cAMP present, using approx. 70,000 CHO cells after incubation for 90 min at 37 °C with [3H]-adenine followed by a 15 min incubation with 1 mM 3-isobutyl-1-methylxanthi
Lyophilized powder containing Tris buffer salts, sodium chloride, sodium azide and sodium EDTA
Toxin consisting of an A subunit (27 kDa) surrounded by five B subunits (approximately 12 kDa each), which attach the toxin to ganglioside GM1 on the cell surface. The A subunit catalyzes ADP-ribosylation of the α-subunit of the stimulatory G protein (Gαs), reducing GTPase activity and activating the α-subunit. This activation of Gαs leads to an increase in the activity of adenylyl cyclase, resulting in increased levels of cAMP. Also ADP-ribosylates transducin in the eye rod outer segments, inactivating its GTPase activity. Cholera toxin has also been reported to ADP-ribosylate tubulin. Shown to be a potent mucosal vaccine adjuvant, inducing T helper cell type 2 responses by inhibiting the production of interleukin-12.
