{"product_id":"nsj-v6084-100ug","title":"HLA-DRA Antibody \/ Major histocompatibility complex class II DR alpha chain, 100ug","description":"\u003cp\u003eHuman leukocyte antigen DR alpha (HLA-DRA) is a major histocompatibility complex class II protein encoded by the HLA-DRA gene and forms the alpha chain of the HLA-DR antigen complex involved in antigen presentation. This molecule pairs with the HLA-DR beta chain to form a heterodimeric receptor that presents processed peptide antigens to CD4-positive T lymphocytes, playing a critical role in adaptive immune responses. HLA-DRA is therefore a central component of the MHC class II antigen presentation pathway and is highly expressed in professional antigen-presenting cells including B lymphocytes, dendritic cells, macrophages, and certain activated epithelial and immune cells.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;HLA-DRA Antibody Recombinant Rabbit MAb for IHC is used to detect expression of the HLA-DR alpha chain in formalin-fixed, paraffin-embedded tissues using immunohistochemistry. In normal tissues, HLA-DR alpha expression is typically observed in antigen-presenting cells within lymphoid organs and inflammatory microenvironments. Immunohistochemical staining often reveals membranous and cytoplasmic signal in B cells, macrophages, dendritic cells, and other immune cell populations involved in antigen processing and presentation. Detection of HLA-DRA by immunohistochemistry therefore provides valuable information about immune activation, antigen presentation, and inflammatory responses within tissue samples.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;The HLA-DR antigen is widely used as a marker of immune activation and antigen-presenting cell identity in both normal and diseased tissues. Because the HLA-DR complex consists of alpha and beta chains encoded by separate genes, antibodies targeting the alpha chain such as HLA-DRA antibody reagents allow specific evaluation of this component of the MHC class II receptor. Expression of HLA-DR alpha is tightly regulated and can be induced by cytokines such as interferon-gamma during immune responses. As a result, HLA-DRA expression frequently increases in inflammatory conditions, infection, autoimmune disease, and tumor microenvironments where immune cell infiltration occurs.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;In diagnostic and research pathology, HLA-DRA antibody staining is frequently used to evaluate immune cell populations and antigen presentation activity within tissues. The HLA-DR alpha chain is commonly detected in lymphoid tissues, sites of inflammation, and tumors with significant immune infiltration. Because HLA-DR expression reflects activation of antigen-presenting pathways, immunohistochemical analysis of HLA-DRA can help characterize immune microenvironments and assess interactions between immune cells and tumor cells. Clone MSVA-470R is a recombinant rabbit monoclonal antibody designed to recognize HLA-DRA and supports detection of the HLA-DR alpha chain in immunohistochemical staining applications.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;This antibody is also part of a broader collection of \u0026lt;a href='\/ihc-antibodies-tissue-microarray-validated.html'\u0026gt;IHC antibodies validated by tissue microarray analysis\u0026lt;\/a\u0026gt;, supporting consistent staining across normal and cancer tissues.\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;\"\u003eV6084-100UG\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;\"\u003eAntibody in 1X PBS with 0.05% BSA, 0.05% sodium azide\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;\"\u003eFormat\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003ePurified\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;\"\u003eClone\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eMSVA-470R\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;\"\u003eHost Animal\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRabbit\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;\"\u003eClonality\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRecombinant Rabbit Monoclonal\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;\"\u003eIsotype\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRabbit IgG, kappa\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;\"\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eHuman\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;\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eIHC\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;\"\u003eApplication Details\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eImmunohistochemistry (FFPE): 1:100-1:200\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;\"\u003eApplication Note\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003e1.
