{"product_id":"nsj-v5909saf-100ug","title":"HLA-E Antibody \/ HLA class I histocompatibility antigen E, 100ug","description":"\u003cp\u003eHLA-E antibody targets HLA class I histocompatibility antigen E, a non-classical major histocompatibility complex class I molecule encoded by the HLA-E gene. HLA-E is primarily localized to the cell surface and functions as an important immune regulatory molecule rather than a classical antigen-presenting HLA protein. Unlike highly polymorphic classical HLA class I molecules such as HLA-A, HLA-B, and HLA-C, HLA-E shows limited polymorphism and serves specialized roles in innate and adaptive immune surveillance.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;HLA class I histocompatibility antigen E is best known for its interaction with inhibitory and activating receptors on natural killer (NK) cells, particularly the CD94\/NKG2 receptor family. By presenting a restricted set of leader sequence-derived peptides from other HLA class I molecules, HLA-E delivers inhibitory signals through CD94\/NKG2A, thereby protecting healthy cells from NK cell-mediated cytotoxicity. For this reason, HLA-E is often described as a non-classical MHC class I molecule and a key ligand involved in immune tolerance and self-recognition. An HLA-E antibody is therefore widely used in studies of NK cell biology and immune checkpoint regulation.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;Beyond NK cell regulation, HLA-E also participates in antigen presentation to subsets of CD8-positive T cells. Certain HLA-E-restricted T cells recognize pathogen-derived peptides, linking HLA-E to antimicrobial and antiviral immune responses. Expression of HLA-E can be upregulated by inflammatory cytokines and cellular stress, further emphasizing its role at the intersection of innate and adaptive immunity. Use of an HLA-E antibody enables investigation of these context-dependent expression patterns in both normal and disease-associated tissues.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;HLA-E expression has gained particular relevance in cancer immunology. Many tumors upregulate HLA class I histocompatibility antigen E as a mechanism of immune evasion, exploiting its inhibitory signaling to suppress NK cell activity. Elevated HLA-E expression has been reported in multiple solid tumors and hematologic malignancies, where it may contribute to reduced immune-mediated tumor clearance. An HLA-E antibody is therefore an important research tool for studying tumor immune escape mechanisms and for evaluating immune checkpoint pathways beyond classical PD-1 or CTLA-4 signaling.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;At the structural level, HLA-E associates with beta-2 microglobulin and binds short peptides derived predominantly from signal sequences of other HLA class I proteins. This restricted peptide repertoire distinguishes HLA-E from classical MHC class I molecules and underlies its specialized immune regulatory function. Because of its defined biology and clinical relevance, HLA-E is frequently examined in studies of transplantation, viral infection, inflammatory disease, and cancer immunotherapy.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;Clone HLAE\/9467 is designed to recognize HLA class I histocompatibility antigen E and supports detection of HLA-E expression in research applications. NSJ Bioreagents offers this HLA-E antibody to support investigations into NK cell regulation, immune tolerance, tumor immunology, and non-classical MHC class I biology.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eCatalog No\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eV5909SAF-100UG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eFamily\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003ePrimary antibody\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eQty\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003e100ug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003e1 mg\/ml in 1X PBS;
