The biological activity of the toxin is produced by the A chain, which activates intracellular adenyl cyclase. Heat-labile enterotoxin B chain Protein, E. coli, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 19.2 kDa and the accession number is P32890.

缓冲液 | If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. |
复溶方法 | Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/mL. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
存储 | Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
运输方式 | In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
研究背景 | The biological activity of the toxin is produced by the A chain, which activates intracellular adenyl cyclase. |
