  • Application notes
    Is unsuitable for IHC-P or WB.
  • Target

    • Function

      Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. Involved in the down-regulation of the immune response and the development of tolerance. Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
    • Tissue specificity

      Expressed on monocytes and B-cells, and at lower levels on dendritic cells. Detected at low levels in natural killer (NK) cells.
    • Sequence similarities

      Contains 4 Ig-like C2-type (immunoglobulin-like) domains.
    • Domain

      Contains 3 copies of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
    • Post-translational

      Phosphorylated on tyrosine residues. Dephosphorylated by PTPN6.

    • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized Human PBMC (human primary peripheral blood mononuclear cell) cells labeling ILT-4 with ab224701 at 1/50 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing co-staining with CD14 and cytoplasmic staining in PBMC cells. The nuclear counterstain is DAPI (blue). Counterstained with an Alexa Fluor® 647 anti-human CD14 antibody at a 1/100 dilution (red).

      The negative control is the secondary antibody only.

      ILT-4 is expressed in monocytes (PMID:10879687) and CD14 is an established marker for monocytes and macrophages (PMID: 23382732).

    • Flow cytometric analysis of human primary peripheral blood mononuclear cell (PBMC) labeling ILT-4 with ab224701 at 1/500 (right panel) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (left panel). Goat anti rabbit IgG (Dylight ® 488, ab98462) at 1/2000 dilution was used as the secondary antibody.

      Cells were stained with Alexa Fluor® 647-conjugated CD14 and rabbit IgG (Left) or ILT-4 (Right).

      Data shown were gated on viable cells.

      The CD14 co-staining result observed is consistent with what has been described in the literature (PMID:10879687).

      ILT-4 is expressed in monocytes and CD14 is an established marker for monocytes and macrophages (PMID: 23382732).
