  Immunocytochemistry/ Immunofluorescence - Anti-HLA-DR antibody [TAL 1B5] (ab20181)

  ab20181 staining HLA DR in Raji cells. The cells were fixed with 4% formaldehyde (10 min), permeabilised in 0.1% Triton X-100 for 5 minutes and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab20181 at 1/1000 dilution and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291, Mouse monoclonal to alpha Tubulin at 1/1000 dilution. Cells were then incubated with Goat Anti-Mouse IgG H&L (Alexa Fluor® 647) preadsorbed ab150119, Goat Anti-Mouse IgG H&L (Alexa Fluor® 647) preadsorbed, at 1/1000 dilution (shown in red) and Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488), preadsorbed at 1/1000 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).
  Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  Western blot - Anti-HLA-DR antibody [TAL 1B5] (ab20181)

  Lanes 1-3: Merged signal (red and green). Green - ab20181 observed at 35 kDa. Red - loading control Anti-GAPDH antibody [EPR16891] - Loading Control ab181602 (Rabbit Anti-GAPDH antibody [EPR16891]) observed at 37 kDa.
  
  ab20181 was shown to react with HLA-DR in Western blot. Membranes were blocked with 3% milk in TBS-T (0.1% Tween®) before incubation with ab20181 and Anti-GAPDH antibody [EPR16891] - Loading Control ab181602 (Rabbit Anti-GAPDH antibody [EPR16891]) overnight at 4°C at 1 µg/ml and a 1:20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1:20000 dilution for 1 h at room temperature before imaging.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-HLA-DR antibody [TAL 1B5] (ab20181)

  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 - Anti-HLA-DR antibody [TAL 1B5] (ab20181)

  Flow cytometry staining of human peripheral blood mononuclear cells (PBMCs) with ab20181 (right) or mouse IgG1κ (Mouse IgG1, kappa monoclonal [15-6E10A7] - Isotype Control 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 (Mouse IgG1, kappa monoclonal [15-6E10A7] - Isotype Control 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) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) preadsorbed 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.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-HLA-DR antibody [TAL 1B5] (ab20181)

  Immunohistochemical analysis of formalin fixed paraffin embedded human tonsil labelling HLA-DR with ab20181 at a concentration of 0.01µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with a OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5 for 32mins.

  ab20181 Anti-HLA-DR antibody [TAL 1B5] was incubated for 16mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

  Customers are encouraged to optimise antigen retrieval conditions, antibody concentration, incubation times and temperature for best results in their own IHC assay workflow (automated and manual).
