Specifications

Our Abpromise guarantee covers the use of ab214966 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Biological activity

    Measured by its ability to stimulate Human T cell proliferation in the presence of anti-CD3.

  • Applications

    Functional Studies

    SDS-PAGE

  • Endotoxin level

    < 0.060 Eu/µg
  • Purity

    > 98 % SDS-PAGE.

  • Form

    Lyophilised
  • Additional notes

    Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcγR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).

     This product was previously labelled as ICOS Ligand

  • Function

    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. Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function.
  • Tissue specificity

    Isoform 1 is widely expressed (brain, heart, kidney, liver, lung, pancreas, placenta, skeletal muscle, bone marrow, colon, ovary, prostate, testis, lymph nodes, leukocytes, spleen, thymus and tonsil), while isoform 2 is detected only in lymph nodes, leukocytes and spleen. Expressed on activated monocytes and dendritic cells.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily. BTN/MOG family.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Cellular localization

    Membrane.
