特徴

• ICOSLG, also known as ICOS ligand isoform a, is a number of the B7 family of co-stimulatory molecules related to B7-1 and B7-2. This protein is a transmembrane glycoprotein with extracellular IgV and IgC domains, and binds to ICOS on activated T cells. Its dependent signaling may play an active role in a proliferative response rather than in cytokine and chemokine production.
• Source:Recombinant protein corresponding to aa19-256 from human ICOSLG, fused to hIgG-His-Tag at C-terminal, expressed in insect cell.
