  • Target

    • Function

      ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through ARHGEF26/SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus.
    • Sequence similarities

      Belongs to the immunoglobulin superfamily. ICAM family.
      Contains 5 Ig-like C2-type (immunoglobulin-like) domains.
    • Post-translational

      Monoubiquitinated, which is promoted by MARCH9 and leads to endocytosis.
    • Cellular localization

    • Expression of proteins with functions involved in ocular disease and wound healing in AM substrates.

      Proteins detected include growth factors and biomarkers (A) cell adhesion, cytokine and angiogenesis markers (B) metalloproteases and (C) neurotrophic factors (D). The collective pattern in staining demonstrates comparable levels of expression in trehalose and raffinose treated AM compared to fresh and increased expression compared to cryopreserved AM. Positive staining is represented as green or yellow and AEC nuclei were counterstained with DAPI (blue). Images shown are representative of triplicate experiments carried out on three donor membranes. Scale bar, 100 µm.

    • ICAM-1 expression on HK-2 cells.

      HK-2 cells (Mock) and HK-2 cells stimulated with TGF-β1 (10.0, 1.0 and 0.1 ng/ml) were stained with ab20 and isotype control mAb (A). HK-2 cells (Mock) and HK-2 cells stimulated with TGF-β1 (10.0 ng/ml) were stained with ab20 and isotype control mAb at 24 hrs, 48 hrs and 72 hrs after TGF-β1 stimulation (B). Cells were analyzed by flow cytometry. Closed histogram: ICAM-1-stained cells. Dotted line: isotype control stained cells. MFI: mean fluorescence intensity.

    • Binding levels of P. falciparum-infected erythrocytes increase after endothelial cell selection.

    Customer reviews and Q&As

    1-3 of 3 Abreviews or Q&A


    Thank you for the response.

    Any monoclonal antibody is produced by a single immune cell, which has been cloned. These will only recognize a single epitope of the target protein. This epitope typically is 5-10 amino acids in length. Therefore any single monoclonal antibody will only recognize a region within a single domain and not stain both the intracellular and extracellular region of the target protein.

    Polyclonal antibodies are created by many different immune cells and will contain multiple epitope recognition sites. Although the amount of antibody specific to a particular epitope will vary from lot-to-lot, it is possible for a polyclonal to therefore contain antibodies which will recognize different domains.

    I have reviewed the antibodies which you have listed as well as other polyclonals in our catalog to try and find a product which might be able to recognize the intracellular and extracellular regions.

    ab2213Anti-ICAM1 antibody [MEM-111]: This monoclonal antibody was created with an immunogen from a whole tissue / cell preparation (Human). We have not mapped the exact location of the epitope. Therefore the epitope recognized might be intracellular, transmembrane or extracellular.

    ab25375Anti-ICAM1 antibody [YN1/1.7.4]: This product is also monoclonal.The details of the immunogen for this antibody are not available. However as a monoclonal, this product will not be able to recognize sites in multiple domains.

    ab7815Anti-ICAM1 antibody (Biotin): This product is a rabbit polyclonal and has been raised against the whole protein. As such it is possible that the product will contain antibodies against both extracellular and intracellular regions. We do not test for this type of response and cannot guarantee that the productwill recognizeboth domains. Please be aware that this product is also biotin labeled.

    Our other rabbit polyclonal antibodies were each created from recombinant fragments and would also not be able to recognize both extracellular and intracellular domains.

    I hope this information is helpful. Please do not hesitate to contact me with further questions.
