		Technical Data
C4275-35Y	Cholera Toxin, beta (Beta Subunit Cholera Toxin, Cholera Enterotoxin beta Chain, Cholera Enterotoxin B Chain, Cholera Enterotoxin gamma Chain, Cholera Enterotoxin Subunit B, Cholera Toxin B Protein, Choleragenoid, CTX B, CTXB, CTX-B, TOXB, VC1456)

Description:
The Beta subunit of cholera toxin binds to a GM1-ganglioside receptor which is widely accepted to initiate toxin action by triggering uptake and delivery of the toxin Alpha subunit into cells. The holotoxin consists of a pentameric ring of Beta subunits whose central pore is occupied by the Alpha subunit. The Alpha subunit contains two chains, A1 and A2, linked by a disulfide bridge. The Alpha subunit (and Cholera toxin) activate the adenylate cyclase enzyme in cells of the intestinal mucosa leading to increased levels of intracellular cAMP.

Applications:
Suitable for use in Immunofluorescence, Immunohistochemistry, ELISA and Western Blot. Other applications not tested.
