Immunohistochemical analysis of paraffin-embedded human skin tissue labeling HLA-DR with ab20181 at 0.1 μg/ml followed by Leica DS9800 (Bond™ Polymer Refine Detection). The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab20181, 0.1ug/ml, for 15 mins at room temperature and was then detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Flow cytometry staining of human peripheral blood mononuclear cells (PBMCs) with ab20181 (right) or mouse IgG1κ (ab170190) isotype (left). PBMCs were incubated for 30 min on ice in 1x PBS containing 10μg/ml human IgG and 10% normal goat serum to block FC receptors and non-specific protein-protein interaction followed by followed by staining with CD19 APC. PBMCs were then fixed in 4.2% formaldehyde and permeabilised in 0.1% saponin before staining with the antibody (ab20181) or mouse IgG1κ (ab170190) isotype (1x106 in 100μl; at 0.008μg/ml) for 30 min on ice. The secondary antibody Goat anti-mouse IgG H&L (Alexa Fluor ® 488, pre-adsorbed) (ab150117) was used at 1 : 2000 dilution for 30 min on ice. Acquisition of >30000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter. Events were gated on alive lymphocytes.

靶点信息

An alpha chain of antigen-presenting major histocompatibility complex class II (MHCII) molecule. In complex with the beta chain HLA-DRB, displays antigenic peptides on professional antigen presenting cells (APCs) for recognition by alpha-beta T cell receptor (TCR) on HLA-DR-restricted CD4-positive T cells. This guides antigen-specific T-helper effector functions, both antibody-mediated immune response and macrophage activation, to ultimately eliminate the infectious agents and transformed cells (PubMed : 15265931, PubMed : 15322540, PubMed : 17334368, PubMed : 22327072, PubMed : 24190431, PubMed : 27591323, PubMed : 29884618, PubMed : 31495665, PubMed : 8145819, PubMed : 9075930). Typically presents extracellular peptide antigens of 10 to 30 amino acids that arise from proteolysis of endocytosed antigens in lysosomes (PubMed : 8145819). In the tumor microenvironment, presents antigenic peptides that are primarily generated in tumor-resident APCs likely via phagocytosis of apoptotic tumor cells or macropinocytosis of secreted tumor proteins (PubMed : 31495665). Presents peptides derived from intracellular proteins that are trapped in autolysosomes after macroautophagy, a mechanism especially relevant for T cell selection in the thymus and central immune tolerance (PubMed : 17182262, PubMed : 23783831). The selection of the immunodominant epitopes follows two processing modes : 'bind first, cut/trim later' for pathogen-derived antigenic peptides and 'cut first, bind later' for autoantigens/self-peptides (PubMed : 25413013). The anchor residue at position 1 of the peptide N-terminus, usually a large hydrophobic residue, is essential for high affinity interaction with MHCII molecules (PubMed : 8145819).
