Biotinylated Human B7-H2/ICOSLG Protein
Recombinant Biotinylated Human B7-H2/ICOSLG Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Asp19-Ser258 [Accession | O75144].
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.
> 95% as determined by Bis-Tris PAGE
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Biotinylated Human B7-H2 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
Immobilized Human ICOS (C136S,C137S), His Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Human B7-H2, His Tag with the EC50 of 25.1ng/ml determined by ELISA.
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.
