  • Function

    Receptor on natural killer (NK) cells for HLA-C alleles (HLA-Cw1, HLA-Cw3 and HLA-Cw7). Inhibits the activity of NK cells thus preventing cell lysis.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily.
    Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
  • Cellular localization

    Cell membrane.

  • Immunohistochemical analysis of paraffin-embedded human endometrium tissue labeling KIR2DL3 with ab225740 at 1/2000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Positive staining in natural killer (NK) cells in human endometrium (PMID: 19628706). Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab225740).


    Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
