General description
Cholera toxin, the pathogenic agent of cholera, is made of two subunits, A (27 kDa) and B (12 kDa) assembled with the stoichiometry AB5. The B-subunit binds to specific receptors, the monosialogangliosides GM1, located in the membrane of intestinal epithelial cells. The A1 fragment of the A-subunit is translocated through the membrane of the host cell, where it catalyses the ADP-ribosylation of the Gsa regulatory component of the adenylate cyclase complex. The resulting increased level of cyclic AMP promotes a wide variety of actions, including the secretion of chloride ions in the case of intestinal epithelial cells.
The antiserum reacts versus Cholera toxin, but shows no reaction versus Staphylococcal enterotoxin A, Staphylococcal enterotoxin B and Pseudomonas exotoxin A (protein concentration: 50-500 ng/dot). The product has not been tested for neutralization potency against active Cholera toxin.
Immunogen
toxin from Vibrio cholerae
Application
Anti-Cholera Toxin antibody produced in rabbit has been used in:
- western blotting
- quantitative ganglioside-dependent enzyme-linked immunoassay (ELISA)
- double immunodiffusion
Biochem/physiol Actions
Cholera toxin (CT), a multifunctional protein plays a role in the immune system. It possesses immunomodulatory, adjuvant properties and also acts as an anti-inflammatory agent. Its immunomodulatory properties can be utilized to treat several autoimmune disorders. CT can serve as one of the best model of a multifunctional protein.
