状态
Lyophilized
溶解方式
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
缓冲液
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
储存条件
4 °C,-80 °C
储存方法
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
CD275, B7H2, B7-H2, B7RP-1, GL50, ICOSL, ICOS-L, ICOSLG, B7RP1, LICOS, ICOS ligand, B7-H2B7-related protein 1, B7RP-1, B7RP1B7-like protein Gl50,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.
分子量
29.5 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
