Applications: This cell line is useful for screening for ICOSL antibodies through flow cytometry, immunocytochemistry or Western blot.
Background: ICOSL is the Ligand for the T-cell-specific cell surface receptor ICOS. When engaged by the ICOSL, the ICOS initiates a costimulatory signal for T-cell proliferation and cytokine production. It also induces B-cell proliferation and differentiation into plasma cells. The ICOS/ICOSL is a major regulator of the adaptive immune responses and also plays an important role in mediating local tissue responses to inflammatory conditions.
