Recombinant Vibriocholerae Toxin B

Mfr.No.	EPT133
Alternative Names	Cholera enterotoxin subunit B;Cholera enterotoxin B chain;Cholera enterotoxin gamma chain;Choleragenoid;ctxB;toxB
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.
Description	Recombinant Vibriocholerae Toxin B is produced by our E.coli expression system and the target gene encoding Thr22-Asn124 is expressed.
Molecular Weight	11.8 KDa
Accession Number	P01556
Endotoxin Level	Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Notes	Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100ug/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Shipping	The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
Purity	Greater than 95%
Storage	Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
