Cat.No. : LT-911E
Product Overview : Type II heat-labile enterotoxin, LT-IIb, from Escherichia coli was produced recombinantly in E. coli and purified to homogeneity using a combination of nickel affinity and gel filtration chromatography. Protein has been His-tagged at the COOH ends of each of the five B subunits.
Description : LT-IIb is a type II heat-labile enterotoxin produced by certain strains of Escherichia coli. The enterotoxin binds to GD1a and to several other gangliosides on the cell surface. The molecule induces high levels of cAMP in the cell upon intoxication. The molecule is also a very strong mucosal and systemic adjuvant when administered by peritoneal, intranasal, or intradermal routes. Single point substitution mutants of LT-IIb are available from Dr. T.D. Connell, upon request, that have altered ganglioside-binding and toxic activities.
