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.

Our Abpromise guarantee covers the use of ab224701 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
FunctionReceptor 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 specificityExpressed on monocytes and B-cells, and at lower levels on dendritic cells. Detected at low levels in natural killer (NK) cells.
Sequence similaritiesContains 4 Ig-like C2-type (immunoglobulin-like) domains.
DomainContains 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.
modificationsPhosphorylated 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).
