  Immunocytochemistry/ Immunofluorescence - Anti-CD31 antibody [EPR3094] (ab76533)

  ab76533 staining CD31 in THP-1 (Human monocytic leukemia monocyte) cell line. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab76533 at 1/250 (4.9 μ μg/mL) overnight at +4°C. ab195889Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used as a counterstain at 1/200 dilution. DAPI (blue) was used as nuclear counterstain.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD31 antibody [EPR3094] (ab76533)

  ab76533 staining CD31 in human muscle tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using citrate buffer pH 6.0. Samples were then blocked with 3% serum for 30 minutes at 20°C followed by incubation with the primary antibody at a 1/200 dilution for 12 hours at20°C. A Cy3®-conjugated goat anti-rabbit polyclonal was used as secondary antibody at a 1/200 dilution.

  OI-RD Scanning - Anti-CD31 antibody [EPR3094] (ab76533)

  We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
  Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD31 antibody [EPR3094] (ab76533)

  Tissue Microarrays stained for "Anti-CD31 antibody [EPR3094]" using "ab76533"in immunohistochemical analysis. This table provides a detailed overview of positive (tick mark) and negative (cross mark) staining per sample type tested. The sections were pre-treated using Heat mediated antigen retrieval using Antigen Retrieval Buffer (100X Tris-EDTA Buffer, pH 9.0) ab93684 (Tris/EDTA buffer, pH 9.0). The sections were incubated with ab76533 at +4°C overnight followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP polymer).

  Panel A: merged staining of anti-CD31 (gray; Opal™690), anti-CD3 epsilon (green; Opal™520) and anti-CD19 (red; Opal™570) on Formalin/PFA-fixed paraffin-embedded sections of human tonsil. Secondary antibody was Opal Polymer HRP Ms + Rb, nuclear counterstain was DAPI.
  Panel B: anti-CD3 epsilon stained on T cells with Anti-CD3 epsilon antibody [SP7] ab16669 at 1/500 dilution
  Panel C: anti-CD19 stained on B cells with Anti-CD19 antibody [SP291] - BSA and Azide free ab237772 at 1/5000 dilution
  Panel D: anti-CD31 stained on endothelial cells and immune cell subsets with Anti-CD31 antibody [EPR3094] - BSA and Azide free ab207090 at 1/500 dilution
  The section was incubated in three rounds of staining: in the order of Anti-CD31 antibody [EPR3094] - BSA and Azide free ab207090 and Anti-CD3 epsilon antibody [SP7] ab16669 for 30 mins, then Anti-CD19 antibody [SP291] - BSA and Azide free ab237772 for 10 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.
  The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins
