Human B7-H3/CD276 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human B7-H3/CD276 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Leu29-Pro245 [Accession | Q5ZPR3-2].

分子量大小(Molecular Weight)

The protein has a predicted MW of 24.7 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.

纯度(Purity)

>95% as determined by Bis-Tris PAGE

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm 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.

产品数据(Assay Data)
Bis-Tris PAGE

Human B7-H3 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

ELISA Data

Immobilized Human B7-H3, His Tag at 1 μg/ml (100 μl/Well) on the plate. Dose response curve for Anti-B7-H3 Antibody, hFc Tag with the EC50 of 9.9 ng/ml determined by ELISA.

背景(Background)

B7-H3, a member of the B7 family of immunomodulatory molecules, is overexpressed in a wide range of solid cancers. B7-H3 binds to activated T cells via an as yet unidentified receptor. In assays using sub-optimal amount so anti-CD3 stimulation, 2Ig‑B7‑H3 enhances T cell proliferation, T cell interferon-gamma (IFN-gamma) production, and cytotoxic T cells induction.

分子别名(Synonyms)

B7H3; B7-H3; CD276; PSEC0249; UNQ309; PRO352; B7 homolog 3; CD276
