  • 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.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of mouse atheroslerotic lesions of aortic root tissue sections labeling ICAM1 with ab119871 at 1/200 dilution. The aortic root was rapidly fixed and harvested at 4°C in phosphate-buffered 4% paraformaldehyde, pH 7.0–7.4, then embedded in paraffin wax sectioned by semi-automated rotary microtome.

  • ab119871 staining ICAM1 in mouse olfactory epithelium tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with 1% paraformaldehyde + lysine + periodate (1% PLP) and permeablized and blocked with 10% donkey serum + 5% nonfat dry milk + 4% BSA + 1% triton X-100. The sample was incubated with primary antibody (1/200) for 1 hour at 27°C. An Alexa Fluor® 488-conjugated donkey anti-rat polyclonal (1/150) was used as the secondary antibody.

  • IHC image of ICAM1 staining in Mouse normal lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with EDTA based pH 9.0 solution, (epitope retrieval solution 2) for 20 mins. The section was then incubated with ab119871, 5µg/ml, for 15 mins at room temperature. A Goat anti-Rat biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for contacting us.

The predicted size, based on the amino acid sequence before any post-translation modifications, is 58 kDa. I do not have the western blot data for this particular antibody, but 58 kDa is the size of the proteins recognized by another ICAM1 antibody, ab20:

On the other hand, other antibodies recognize bands at higher molecular weights, which may represent glycosylated ICAM1, as seen for example in the blot on the datasheet for ab109361:

Thanks you for your email.
In my previous email there is a correction about the expiry date. The expiry date should be read as 25-08-2012.
I have asked lab to release the immunogen information of these antibodies; I will be able to send the answer to your question soon.
Many thanks for having patience!
