Knockout Validation of CD31/PECAM-1 Antibody in THP-1 Cells by Immunocytochemistry/Immunofluorescence

CD31/PECAM-1 was detected in immersion fixed THP-1 (red, positive) but not THP-1 KO (negative) cells using 8 ug/mL Mouse Anti-Human CD31/PECAM-1 (JC/70A) Monoclonal Antibody (Catalog # NB600-562) for 3 hours at room temperature. Cells were stained with the NorthernLights(TM) 557-conjugated Donkey anti-Mouse IgG Secondary Antibody (red, Catalog # NL007)) and and counterstained with DAPI (blue).

Formalin-fixed paraffin-embedded tissue sections of human metastatic tonsil were probed for CD31 mRNA (ACD RNAScope probe, catalog # 487381; Fast Red chromogen, ACD catalog # 322500). Adjacent tissue section was processes for immunohistochemistry using mouse monoclonal (NB600-562) at 1:25 dilution for 1 hour at room temperature followed by incubation with the anti-mouse IgG VisUCyte HRP Polymer Antibody (Catalog # VC001) and DAB chromogen (yellow-brown). Tissue was counterstained with hematoxylin (blue).

Application Notes
This CD31/PECAM1 Antibody (JC/70A) is useful for IHC on paraffin-embedded sections, Flow cytometry and Western blot. It reacts with an ~100 kDa glycoprotein expressed by endothelial cells and ~130 kDa glycoprotein present in platelets. It stains endothelial cells in normal as well as malignant tissues. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended. Use in ELISA reported in scientific literature (PMID: 8307606).

Background: CD31/PECAM-1

Cluster of differentiation (CD31), Platelet Endothelial Cell Adhesion Molecule 1 (PECAM-1), is a 30kDa type I transmembrane glycoprotein expressed by endothelial cells, platelets, leukocytes and some lymphocytes (e.g., B and T-cell subsets). Structurally, PECAM-1 consists of six extracellular immunoglobulin-like domains which serve to support various functions including homophilic binding, maintaining high expression of PECAM-1 within endothelial intercellular junctions, and supporting endothelial cell migration (1,2). PECAM's homophilic binding underscores its role in vascular barrier integrity and leukocyte trans-endothelial movement. However, PECAM may also engage in heterophilic interactions with molecules such as glycosaminoglycans (GAG), integrin alpha 5 beta 3, CD38 in lymphocytes and CD177/PR3 in neutrophils (2).

PECAM's intracellular cytoplasmic domain consists of a sequence of 118 amino acids and contains serine and tyrosine (also referred to as immunoreceptor tyrosine-based inhibitory motifs-ITIMs) residues, which may be phosphorylated upon cellular stimulation (3). ITIMs are phosphorylated by Src-family kinases and non-Src family kinases (e.g., Csk), leading to a conformational change which supports interactions with Src homology 2 (SH2) domain containing proteins such as protein-tyrosine phosphatase, SHP-2 (1,2). Formation of SHP-2/PECAM-1 complexes induces endothelial cell migration through the dephosphorylation of focal adhesion kinase and regulation of RhoA activity (1). Signaling downstream of ITIM tyrosine phosphorylations also plays a role in PECAM's anti-apoptotic activity, a function which is independent of its interaction with SHP-2. In platelets and leukocytes, phosphorylation of PECAM's cytosolic domain is inhibitory, preventing their activation.
