Biotinylated Human IL-23 alpha&IL-12 beta Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Human IL-23 alpha&IL-12 beta Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.
It contains Arg20-Pro189 (IL-23 alpha) and Ile23-Ser328 (IL-12 beta) [Accession | Q9NPF7(IL-23 alpha)&P29460(IL-12 beta)].

分子量大小(Molecular Weight)

The protein has a predicted MW of 21.7 kDa (IL-23 alpha) and 34.7 kDa (IL-12 beta). Due to glycosylation, the protein migrates to 24 kDa (IL-23 alpha) and 40-50 kDa (IL-12 beta) based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(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.

背景(Background)

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.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
