Applications

Our Abpromise guarantee covers the use of ab76533 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/5000 - 1/20000. Predicted molecular weight: 83 kDa.
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.

We suggest to program the pressure cooker to run for 30 seconds at 125° C, followed by 10 seconds at 90° C. Then let the slide cool down to room temperature (10 - 20 minutes).

  • Application notesIs unsuitable for Flow Cyt,ICC/IF or IP.
  • Target

    • FunctionInduces susceptibility to atherosclerosis (By similarity). Cell adhesion molecule which is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions. Tyr-690 plays a critical role in TEM and is required for efficient trafficking of PECAM1 to and from the lateral border recycling compartment (LBRC) and is also essential for the LBRC membrane to be targeted around migrating leukocytes. Prevents phagocyte ingestion of closely apposed viable cells by transmitting 'detachment' signals, and changes function on apoptosis, promoting tethering of dying cells to phagocytes (the encounter of a viable cell with a phagocyte via the homophilic interaction of PECAM1 on both cell surfaces leads to the viable cell's active repulsion from the phagocyte. During apoptosis, the inside-out signaling of PECAM1 is somehow disabled so that the apoptotic cell does not actively reject the phagocyte anymore. The lack of this repulsion signal together with the interaction of the eat-me signals and their respective receptors causes the attachment of the apoptotic cell to the phagocyte, thus triggering the process of engulfment). Isoform Delta15 is unable to protect against apoptosis. Modulates BDKRB2 activation. Regulates bradykinin- and hyperosmotic shock-induced ERK1/2 activation in human umbilical cord vein cells (HUVEC).
    • Tissue specificityExpressed on platelets and leukocytes and is primarily concentrated at the borders between endothelial cells. Isoform Long predominates in all tissues examined. Isoform Delta12 is detected only in trachea. Isoform Delta14-15 is only detected in lung. Isoform Delta14 is detected in all tissues examined with the strongest expression in heart. Isoform Delta15 is expressed in brain, testis, ovary, cell surface of platelets, human umbilical vein endothelial cells (HUVECs), Jurkat T-cell leukemia, human erythroleukemia (HEL) and U937 histiocytic lymphoma cell lines (at protein level).
    • Sequence similaritiesContains 6 Ig-like C2-type (immunoglobulin-like) domains.
    • DomainThe Ig-like C2-type domains 2 and 3 contribute to formation of the complex with BDKRB2 and in regulation of its activity.
    • Post-translational
      modifications
      Phosphorylated on Ser and Tyr residues after cellular activation. In endothelial cells Fyn mediates mechanical-force (stretch or pull) induced tyrosine phosphorylation.
    • Cellular localizationMembrane. Cell junction. Localizes to the lateral border recycling compartment (LBRC) and recycles from the LBRC to the junction in resting endothelial cells and Cell junction. Localizes to the lateral border recycling compartment (LBRC) and recycles from the LBRC to the junction in resting endothelial cells.

    • Immunohistochemical analysis of endothelial colony forming progenitor cell plugs, staining CD31 (green) with ab76533.

      Following antigen retrieval and blocking, sections were incubated with primary antibody (1/1000) overnight at 4°C. A Cy5®-conjugated anti-rabbit IgG (2 µg/ml) was used as the secondary antibody.
    • ab76533 staining CD31 in human kidney tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/100. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at a dilution of 1/500.

    Ab76533, a rabbit monoclonal antibody to CD31, has been tested and shown to cross-react with human but not with mouse or rat. This should be the perfect antibody for you to use in your xenograft studies.

    Vielen Dank für die zwei Sequenzen von Lachs (Salmo salar).
    Ich habe beide mit den Immunogenen aller unserer CD31 Antikörper aus dem Kaninchen verglichen.
    Leider hat keine Immunogensequenz auch nur annähernd eine Homologie grösser als ein paa...
