HLA-DRB1 antibody

Catalog No. ABIN6186381

Product Details anti-HLA-DRB1 Antibody

Target: HLA-DRB1 (Major Histocompatibility Complex, Class II, DR beta 1 (HLA-DRB1))

Reactivity: Human, Monkey

Host: Mouse

Clonality: Monoclonal

Conjugate: This HLA-DRB1 antibody is un-conjugated

Application: Western Blotting (WB), Flow Cytometry (FACS), Immunofluorescence (IF), Immunostaining (ISt), Immunohistochemistry (Formalin-fixed Sections) (IHC (f))

Purpose: Mouse Monoclonal anti-HLA-DRB (HLA-DRB/1067), Purified, BSA-free

Characteristics: This MAb reacts with the beta-chain of HLA-DRB1 antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. Its epitope is different from that of MAb L243. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kDa alpha (heavy) chain and a 28 kDa beta (light) chain. It is expressed on B-cells, activated T-cells, monocytes/macrophages, dendritic cells and other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 Molecules, HLA-DR is critical for efficient peptide presentation to CD4 T cells. It is an excellent histiocytic marker in paraffin sections producing intense cytoplasmic staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts. Loss of HLA-DR expression is related to tumor microenvironment and predicts adverse outcome in diffuse large B-cell lymphoma. Primary antibodies are available purified, or with a selection of fluorescent CF® dyes and other labels. CF® dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
