Human B7-H3/CD276 Protein
Recombinant Human B7-H3/CD276 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Leu29-Pro245.[Accession | Q5ZPR3-2]
The protein has a predicted MW of 24.7 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22μm 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 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human B7-H3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
The purity of Human B7-H3 is greater than 95% as determined by SEC-HPLC.
Immobilized Human B7-H3, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-B7-H3 Antibody, hFc Tag with the EC50 of 29.4ng/ml determined by ELISA.
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.
