B7-2 Protein, Cynomolgus, Recombinant (His)

B7-1 and B7-2 are homologous costimulatory ligands expressed on the surface of antigen presenting cells (APCs). Binding of these molecules to the T cell costimulatory receptors, CD28 and CTLA-4, is essential for the activation and regulation of T cell immunity. B7-1 and B7-2 do not form hetero-oligomers, underscoring the biological relevance of dimeric and monomeric state of B7-1 and B7-2, respectively. B7-2 Protein, Cynomolgus, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 26.4 kDa and the accession number is G7NXR4.

标签	C-His
蛋白编号	G7NXR4
别名	B72, MGC34413, LAB72, B7-2, FUN-1, B7-2 antigen, CD86, BU63, CD28LG2, B70, CD86 molecule
蛋白构建	Tyr26-His240
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	26.4 kDa (predicted). Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.

内毒素	< 1 EU/μg by the LAL method.
缓冲液	Lyophilized 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.
复溶方法	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.
存储	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℃. For reconstituted proteinsolutions, 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.
运输方式	In general, Lyophilized powders are shipping with blue ice.
