  • FunctionIntegrin alpha-L/beta-2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4. It is involved in a variety of immune phenomena including leukocyte-endothelial cell interaction, cytotoxic T-cell mediated killing, and antibody dependent killing by granulocytes and monocytes.
  • Tissue specificityLeukocytes.
  • Sequence similaritiesBelongs to the integrin alpha chain family.
    Contains 7 FG-GAP repeats.
    Contains 1 VWFA domain.
  • DomainThe integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.
  • Cellular localizationMembrane.

Anti-CD11a antibody [EP1285Y] images

  • Immunohistochemical analysis of paraffin-embedded Human squamous cell cervical carcinoma labeling CD11a with ab52895 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab79051) at 1/500 dilution. Membrane/cytoplasmic staining on stromal inflammatory cells of human cervical cancer is observed. The negative control utilised PBS instead of primary antibody. Counter stained with Hematoxylin.

  • Immunohistochemical analysis of paraffin-embedded Human tonsil labeling CD11a with ab52895 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab79051) at 1/500 dilution. Membrane/cytoplasm staining on lymphocytes of human tonsil is observed. The negative control utilised PBS instead of primary antibody. Counter stained with Hematoxylin.

  • Immunohistochemical analysis of cynomolgus monkey brain tissue, staining CD11a with ab52895 at 1/50 dilution.
  • All lanes : Anti-CD11a antibody [EP1285Y] (ab52895) at 1/5000 dilution

    Lane 1 : Jurkat (Human T cell leukemia cells from peripheral blood) whole cell lysates
    Lane 2 : THP-1 (Human monocytic leukemia cells) whole cell lysates

    Lysates/proteins at 20 µg per lane.

    Goat Anti-Rabbit IgG, (H+L),Peroxidase conjugated at 1/1000 dilution

    Predicted band size : 129 kDa
    Additional bands at : 180 kDa (possible glycosylated form).

    Blocking and Dilution buffer: 5% NFDM/TBST


    The band in THP-1 cells is higher than that in Jurket cells due to the different glycosylation level in different materials.

  • CD11a was immunoprecipitated from 1mg of Jurkat(Human T cell leukemia cells from peripheral blood) whole cell lysates using ab52895 at 1/50 dilution. Western blot was performed from the immunoprecipitate using ab52895 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1000 dilution.
    Blocking and dilution buffer and concentration: 5% NFDM/TBST.


  • Flow cytometry analysis of 2% paraformaldehyde fixed Jurkat (Human T cell leukemia cells from peripheral blood) cells labeling CD11a with ab52895 at 1/50 dilution (red line). Secondary antibody used is a goat anti rabbit IgG (FITC) at 1/150 dilution. The isotype control is rabbit monoclonal IgG (black line). The unlabeled control is cells without incubation with primary and secondary antibodies (blue line).
