Human IL-12 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human IL-12 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.
It contains Ile23-Ser328 (IL-12B) & Arg23-Ser219 (IL-12A) [Accession | P29460(IL-12B)&P29459(IL-12A)].

分子量大小(Molecular Weight)

The protein has a predicted MW of 34.7 kDa(IL-12B) & 25.5 kDa(IL-12A). Due to glycosylation, the protein migrates to 40-45 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by SEC-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)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

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.

产品数据(Assay Data)
Bis-Tris PAGE

Human IL-12 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human IL-12 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human IL-12, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-IL-12 Antibody, hFc Tag with the EC50 of 2.4ng/ml determined by ELISA (QC Test).

Cell Based Assay

Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is 0.1 - 1 ng/mL.

背景(Background)

Interleukin 12 (IL-12) is a pleiotropic cytokine that plays an essential role in Th1-type immune response against cancer, a condition where cells in a particular part of the body grow and reproduce uncontrollably.

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