- Extra Details:
- Heat-labile enterotoxin is a type of labile toxin found in Escherichia coli that is inactivated at high temperatures. It acts similarly to the cholera toxin by raising cAMP levels through ADP-ribosylation of the alpha-subunit of a Gs protein leading to the constitutive activation of adenylate cyclase. Elevated cAMP levels stimulate secretion of Chloride ions and water from the enterocyte into the gut lumen, thus causing watery diarrhea. In addition to its effects on chloride secretion, which involve the same steps as the effects of cholera toxin, heat-labile enterotoxin binds additional substrates: lipopolysaccharide on the surface of E. coli cells and A-type blood antigens. The importance of these binding events is not yet known. Applications: Suitable for use in ELISA. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
