CD31 (PECAM-1) Antibody in Immunocytochemistry (ICC) — Immunofluorescence analysis of Platelet endothelial cell adhesion molecule was performed using 70% confluent log phase HUVEC cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with CD31 (PECAM-1) Monoclonal Antibody (WM-59 (WM59)), eFluor 450, eBioscience™ (Product # 48-0319-41, 48-0319-42) at 5ug/ml in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b: Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300 dilution). Panel d represents the merged image showing Cell Junctional localization. Panel e represents no expression in MDA-MB-231. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

CD31 (PECAM-1) Antibody in Western Blot (WB) — Western blot was performed using Anti-CD31 (PECAM-1) Monoclonal Antibody (WM-59 (WM59)), eFluor 450, eBioscience™ (Product # 48-0319-41, 48-0319-42) and a 130kDa band corresponding to Platelet endothelial cell adhesion molecule was observed across cell lines tested. Membrane enriched extracts (40 µg lysate) of HUVEC (Lane 1), MDA-MB-231 (Lane 2), THP-1 (Lane 3) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (0.5ug/ml) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076).

CD31 (PECAM-1) Antibody in Flow Cytometry (Flow) — Staining of normal human peripheral blood cells with Mouse IgG1 K Isotype Control eFluor® 450 (Product # 48-4714-82) (blue histogram) or Anti-Human CD31 (PECAM-1) eFluor® 450 (purple histogram). Cells in the monocyte gate were used for analysis.

CD31 (PECAM-1) Antibody in Relative expression — Antibody specificity was demonstrated by detection of differential basal expression of the target across cell lines tested owing to their inherent genetic constitution. Relative expression of Platelet endothelial cell adhesion molecule was observed to be high in HUVEC in comparison to no expression in MDA-MB-231 using Anti-CD31 (PECAM-1) Monoclonal Antibody (WM-59 (WM59)), eFluor 450, eBioscience™ (Product # 48-0319-41, 48-0319-42) in Western Blot (Ref :https://www.nature.com/articles/onc2013214). {RE}

Product Specific Information

Description: The WM59 monoclonal antibody reacts with human CD31, also known as platelet-endothelial cell adhesion molecule-1 (PECAM-1) and gpIIa. This 130-140 kDa surface protein is expressed by endothelial cells and at low levels on leukocytes and platelets. It has been reported that CD38 binds to CD31. Homotypic interaction of CD31 is important in adhesion, cell-cell and cell-matrix interaction, and signal transduction.

Applications Reported: This WM-59 (WM59) antibody has been reported for use in flow cytometric analysis.

Applications Tested: This WM-59 (WM59) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capable of detecting this fluorochome.

Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

CD31 (platelet endothelial cell adhesion molecule-1, PECAM-1) is an inhibitory coreceptor involved in regulation of T cell and B cell signaling by a dual immunoreceptor tyrosine-based inhibitory motif (ITIM) that upon associated kinases-mediated phosphorylation provide docking sites for protein-tyrosine phosphatases. CD31 is expressed ubiquitously within the vascular compartment and is located mainly at junctions between adjacent cells. N-terminal Ig-like domain of CD31 is responsible for its homophilic binding, which plays an important role in cell-cell interactions. CD31 is a multifunctional molecule with diverse roles in modulation of integrin-mediated cell adhesion, transendothelial migration, angiogenesis, apoptosis, negative regulation of immunoreceptor signaling, autoimmunity, macrophage phagocytosis, IgE-mediated anaphylaxis and thrombosis. It is one of key regulatory molecules in vascular system.
