		Technical Data
C4275-35V	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 B subunit of cholera toxin (CtxB) binds to a GM1-ganglioside receptor, a ubiquitous glycolipid cell surface receptor. This binding is widely accepted to initiate toxin action by triggering uptake and delivery of the toxin A subunit into cells. The beta chain has no toxic activity by itself. The holotoxin consists of a pentameric ring of B subunits whose central pore is occupied by the A subunit. The A subunit contains two chains, A1 and A2, linked by a disulfide bridge.

The A subunit (and Cholera toxin) activates the adenylate cyclase enzyme in cells of the intestinal mucosa leading to increased levels of intracellular cAMP.

Applications:
Suitable for use in ELISA. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
