Recombinant Human ICOSLG protein, His-Avi-tagged

Specification :
| Description : 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. | Source : HEK293 | Species : Human | Tag : His-Avi | Form : Supplied as 0. 22um filtered solution in PBS (pH 7. 4). | Molecular Mass : The protein has a predicted MW of 29. 5 kDa. Due to glycosylation, the protein migrates to 55-70 KDa based on Bis-Tris PAGE result | Protein length : Asp19-Ser258 | Endotoxin : Less than 0. 05 EU per ug by the LAL method. | Purity : > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC | Storage : The product should be stored at -70°C. Please do not repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
