  • Description
    Inducible co-stimulator ligand (ICOSL), also known as B7-H2, is a member of the B7 family of co-stimulatory molecules related to B7-1 and B7-2. It is a transmembrane glycoprotein with extracellular IgV and IgC domains, and binds to ICOS on activated T cells, thus delivers a positive costimulatory signal for optimal T cell function. The structural features of ICOSL are crucial for its costimulatory function. Present study shows that ICOSL displays a marked oligomerization potential, resembling more like B7-1 than B7-2. B7-H2-dependent signaling may play an active role in a proliferative response rather than in cytokine and chemokine production. The CD28/B7 and ICOS/B7-H2 pathways are both critical for costimulating T cell immune responses. Deficiency in either pathway results in defective T cell activation, cytokine production and germinal center formation.

  • Uniprot ID
    Q9JHJ8
  • Gene Name
    Icosl; mCG_5977
  • Source/Expression Host
    Human Cells
  • Expression Plasmid/cDNA
    A DNA sequence encoding the mouse B7-H2 (NP_056605.1) extracellular domain (Met 1-Lys 279) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
  • Protein Species
    Mouse
  • Molecular weight
    The secreted recombinant mouse B7-H2/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer comprises 481 amino acids with a predicted molecular mass of 54.3 kDa. As a result of glycosylation, it migrates as an approximately 75-85 kDa band in SDS-PAGE under reducing conditions.
  • Purity
    > 95 % as determined by SDS-PAGE
  • Activity
    Measured by its binding ability in a functional ELISA. Immobilized human ICOS at 1 μg/ml (100 μl/well) can bind biotinylated mouse B7-H2 Fc chimera with a linear range of 0.125-1.0 μg/ml.
