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.

蛋白构建 | Recombinant Vibriocholerae Toxin B is produced by our E.coli expression system and the target gene encoding Thr22-Asn124 is expressed. |
蛋白纯度 | Greater than 95% as determined by reducing SDS-PAGE. (QC verified) |
分子量 | 11 KDa, reducing conditions |
内毒素 | Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
缓冲液 | Lyophilized from a 0.2 μm filtered solution of 50mM Tris-HCl, 200mM NaCl, pH 8.0. |
复溶方法 | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
存储 |
Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months. |
运输方式 |
The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. |
