  • 特記事項


    The antibody is useful for detection of HLA-DR and HLA-DP positive B-cells, T-cells and monocytes in cell suspensions, in frozen sections as well as in formalin fixed paraffin embedded tissue sections. The antibody is also useful for characterization of leukemias and lymphomas. In experimental settings it can be used for selective removal of antigen carrying cells by complement mediated cytotoxicity. The antibody has excellent staining properties in histology.

    Human MHC class II antigens are transmembrane glycoproteins composed of an alpha (36 kDa) and a beta chain (27kDa) and are expressed primarily on antigen presenting cells. Human MHC class II genes are located in the HLA-D region that encodes at least 6 alpha and 10 beta chain genes. Three loci, DR, DQ and DP, encode the major products of the human class II region. The human MHC class II molecules bind intracellularly processed peptides and present them to T-helper cells and therefore have a critical role in the initiation of the immune response. It has been shown that some autoimmune diseases are associated with certain class II alleles.

Anti-HLA DR + HLA DP antibody [HL-40] 画像

  • Human peripheral blood lymphocytes stained with ab8085 (red line). Human whole blood was processed using a modified protocol based on Chow et al, 2005 (PMID: 16080188). In brief, human whole blood was fixed in 4% formaldehyde (methanol-free) for 10 min at 22°C. Red blood cells were then lyzed by the addition of Triton X-100 (final concentration - 0.1%) for 15 min at 37°C. For experimentation, cells were treated with 50% methanol (-20°C) for 15 min at 4°C. Cells were then incubated with the antibody (ab8085, 0.01μg/1x106 cells) for 30 min at 4°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 4°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >30,000 total events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. Gating strategy - peripheral blood lymphocytes.

  • HeLa cells were transfected with DR. The cells were fixed in paraformaldehyde and either left unpermeabilized (-Tx) or were permeabilized with 0.2% Triton X-100 (+Tx). DR- and DP-transfected cells were immunostained with ab8085. Nuclei were stained with DAPI.
  • HeLa cells were transfected with different combinations of a, ß, and Ii constructs as indicated. Lysates were first subjected to immunoprecipitation (IP) with ab8085 before Western blotting (WB) with anti-DP and anti-Ii. H and L indicate the heavy and light chains of the antibodies used for the immunoprecipitation.
