B7-H2/ICOSLG Protein, Human, Recombinant (His & Avi)

产品编号 TMPK-00192

B7-H2, also known as B7-related protein (B7RP1), ICOS Ligand, and CD275, is an approximately 60 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. B7-H2 is a ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. B7-H2/ICOSLG Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 29.5 kDa and the accession number is O75144.

别名	LICOS,ICOSLG,ICOS-L,ICOSL,ICOS ligand,GL50,CD275,B7RP1B7-like protein Gl50,B7RP-1,B7RP1,B7-H2B7-related protein 1,B7-H2,B7H2
蛋白构建	Asp19-Ser258
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	29.5 kDa (predicted). Due to glycosylation, the protein migrates to 55-70 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°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.
运输方式	In general, Lyophilized powders are shipping with blue ice.
