    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing.

Target

  • 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.
  • Target information above from: UniProt accession O75144 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010

      Immunoprecipitation - Anti-ICOS Ligand/ICOSL antibody [EPR20240] (ab209262)

      ICOS Ligand/ICOSL was immunoprecipitated from 0.35 mg of JAR (Human placenta choriocarcinoma cell line) whole cell lysate with ab209262 at 1/40 dilution. Western blot was performed from the immunoprecipitate using ab209262 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

      Lane 1: JAR whole cell lysate, 10 μg (Input).

      Lane 2: ab209262 IP in JAR whole cell lysate.
