Scientific Data Images for Human CD31/PECAM-1 Antibody

Detection of CD31 in Human Prostate Cancer via seqIF™ staining on COMET™

CD31 Antibody was detected in immersion fixed paraffin-embedded sections of human Prostate Cancer using Rabbit Anti-Human CD31, Monoclonal Antibody (Catalog #MAB11678) at 8ug/mL at 37° Celsius for 2 minutes. Before incubation with the primary antibody, tissue underwent an all-in-one dewaxing and antigen retrieval preprocessing using PreTreatment Module (PT Module) and Dewax and HIER Buffer H (pH 9; Epredia Catalog # TA-999-DHBH). Tissue was stained using the Alexa Fluor™ Plus 555 Goat anti-Rabbit IgG Secondary Antibody at 1:100 at 37 ° Celsius for 2 minutes. (Yellow; Lunaphore Catalog # DR555RB) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane of endothelial cells. Protocol available in COMET™ Panel Builder.​​

Detection of Human CD31/PECAM-1 by Western Blot.

Western Blot shows lysates of THP-1 human acute monocytic leukemia cell line. PVDF membrane was probed with 1 µg/ml of Rabbit Anti-Human CD31/PECAM-1 Monoclonal Antibody (Catalog # MAB11678) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for CD31/PECAM-1 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of CD31/PECAM-1 in Human Colon.

CD31/PECAM-1 was detected in immersion fixed paraffin-embedded sections of human colon using Rabbit Anti-Human CD31/PECAM-1 Monoclonal Antibody (Catalog # MAB11678) at 3 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC003) or the HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). 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 the membrane.

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 alphav beta3 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.
