背景	Inducible T-cell costimulator (CD278/ICOS) is a ~22 kDa protein. Stimulatory receptor expressed in activated or antigen-experienced T-cells that plays an important role in the immune response. Upon binding to its ligand ICOSL expressed on antigen presenting cells (APCs), delivers costimulatory signals that enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines including IL10, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells. Also acts as a costimulatory receptor critical for the differentiation of T follicular regulatory cells upon immune challenges such as viral infection. Mechanistically, potentiates TCR-induced calcium flux by augmenting PLCG1 activation and actin remodeling. In addition, activates PI3K signaling pathways independently of calcium flux. 1.

Bioactivity

SEC-HPLC detection for Research Grade Vopratelimab.
SDS-PAGE

SDS-PAGE for Research Grade Vopratelimab.
Flow CytoMetry

Flow-cytometry using anti-human CD278 antibody. Untransfected cells (blue Histogram) and Transfected cells (Yellow Histogram) were stained with an anti-human CD278 monoclonal antibody (Catalog: HV702016) at a concentration of 5 µg/ml for 30 mins at RT. After washing, bound antibody was detected using a Goat Anti-Human IgG H&L Polyclonal Antibody, FITC (abinScience: HF690414) and cells analysed on a NovoCyte Flow Cytometer.
Western blot

Western blot analysis was performed using anti-CD278/ICOS monoclonal antibody at 1ug/mL on various samples.
