B7-H3 (4Ig) /B7-H3b Protein, Human, Recombinant (His & Avi)

TargetMol | SPR
Catalog No. TMPK-00314 Copy Product Info
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. B7-H3 (4Ig) /B7-H3b Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 49.5 kDa and the accession number is Q5ZPR3-1.

Construction
Gly27-Thr461
Protein Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight49.5 kDa (predicted). Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result.
Endotoxin< 1.0 EU/μg of the protein as determined by the LAL method.
FormulationLyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution
Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
ShippingIn general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
