View LargerDetection of Human CD31/PECAM‑1 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human CD31/PECAM-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF806) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for CD31/PECAM-1 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

CD31/PECAM-1 was detected in immersion fixed HUVEC human umbilical vein endothelial cells using 10 µg/mL Sheep Anti-Human CD31/PECAM-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF806) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

CD31/PECAM‑1 was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line but is not detected in CD31/PECAM‑1 knockout (KO) THP‑1 human cell line using Sheep Anti-Human CD31/PECAM‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF806) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; NL010) and counterstained with DAPI (blue). Specific staining was localized to cell membrane. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.
View LargerDetection of CD31/PECAM‑1 in human liver. CD31/PECAM‑1 was detected in immersion fixed paraffin-embedded sections of human liver using Sheep Anti-Human CD31/PECAM‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF806) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to endothelial cells.

H&E staining of normal exocrine pancreas with acini structures and a duct in the insert. The area shown is representative for all panels in B. B. Merged immunofluorescence staining of integrin alpha 1, alpha 2, and beta 1 (in red), and type IV collagen (green in upper row), or the endothelial marker CD31 (green in lower row). Type IV collagen is present in the vascular-, ductal-, and acini-BMs. Integrin alpha 1 is only expressed in endothelial cells and integrin alpha 2 only in the ductal epithelium. Integrin beta 1 is found in the ductal-, endothelial-, and at the base of the acini-cells. Arrows indicate examples of colocalization. Magnification x40 in all panels. Cell nuclei are stained by DAPI (in blue).

Background: CD31/PECAM-1
The CD31 adhesion molecule, also known as PECAM-1, is expressed in large amounts on endothelial cells at intercellular junctions and on T cell subsets, and to a lesser extent on platelets and most other leukocytes such as monocytes and neutrophils. CD31 binds to itself homotypically, and also to the leukocyte integrin alpha v beta 3 heterotypically. CD31 is required for the transendothelial migration of leukocytes through intercellular junctions of vascular endothelial cells. CD31 has been found in human plasma, and the presence of this circulating isoform is suggested to modulate the transendothelial migration of leukocytes.
