Human IL-23 alpha&IL-12 beta Protein
Recombinant Human IL-23 alpha&IL-12 beta Protein is expressed from HEK293 with His tag at the C-terminus.It contains Arg20-Pro189(IL-23 alpha) & Ile23-Ser328(IL-12 beta) [Accession | Q9NPF7(IL-23 alpha)&P29460(IL-12 beta)].
The protein has a predicted MW of 19.77 kDa (IL-23 alpha) and 34.7 kDa (IL-12 beta). Due to glycosylation, the protein migrates to 23 kDa (IL-23 alpha) and 40-50 kDa (IL-12 beta) based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-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.

The interleukin (IL)-12 family of cytokines, including IL12 and IL 23, play an important role in driving aberrant Th1 and Th17 immune responses in patients with Crohn's disease (CD). Targeting this pathway has opened new avenues for therapeutic intervention. The balance of proinflammatory cytokines interleukin (IL)-12 and IL-23 plays a key role in shaping the development of antitumor or protumor immunity.
