- Description
| Specificity Profile | More Information |
 | The specificity of CD31 Monoclonal Antibody (CSB0021) was tested on the Membrane Proteome Array™ and shown to be specific for human CD31. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |
| Application | Conditions | Recommended Concentration |
| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/ml |
 | HEK-293F cells transiently transfected with human CD31 were stained with CD31 Monoclonal Antibody (CSB0021) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with CD31 Monoclonal Antibody (CSB0021) (blue). | |

CD31 is a single-pass transmembrane protein, cell adhesion molecule, and member of the immunoglobulin superfamily found on the surface of platelets, monocytes, neutrophils, and some types of T-cells. CD31 may play a role in leukocyte migration, angiogenesis, and integrin activation. (NCBI Gene: 5175, UniProtKB/Swiss-Prot: P16284). Other names: PECAM1, PECAM-1, EndoCAM, GPIIA', PECA1, CD31/EndoCAM
