Abbreviation:
Choleragenoid;CTXB;toxB
Accession:
P01556
Background:
Cholera toxin is protein complex secreted by the bacterium Vibrio cholerae. It is responsible for the massive, watery diarrhea characteristic of cholera infection. Cholera enterotoxin subunit B (CTXB) pentameric ring directs the A subunit to its target by binding to the GM1 gangliosides present on the surface of the intestinal epithelial cells. It can bind five GM1 gangliosides. It has no toxic activity by itself.
Calculated MW:
11.8 kDa
Endotoxin:
< 1.0 EU per ug of the protein as determined by the LAL method.
Expression Host:
E.coli
Formulation:
Lyophilized from a 0.2 um filtered solution of 50mM Tris, 200mM NaCl, pH8.0.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Fusion tag:
None
ObservedMW:
11 kDa
Purity:
> 95 % as determined by reducing SDS-PAGE.
Sequence:
Thr22-Asn124
