Non-biotinylated Human IL-23 alpha&Mouse IL-12 beta Protein, Ultra Low Endotoxin (ILB-HM4AB-UL) Summary
Product Description |
Recombinant Human IL-23 alpha&Mouse IL-12 beta Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus of IL-23 alpha.It contains Arg20-Pro189(Human IL-23 alpha) and Met23-Ser335(Mouse IL-12 beta). |
Product Background |
Interleukin (IL)-12 and IL-23 belong to the IL-12 type family and are composite cytokines, consisting of the common β subunit p40 and the specific cytokine α subunit p35 and p19, respectively. IL-12 signals via the IL-12Rβ1·IL-12Rβ2 receptor complex, and IL-23 uses also IL-12Rβ1 but engages IL-23R as second receptor. |

Shipping, Reconstitution, & Storage
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
Stability And Storage |
-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
