Immunohistochemistry on Frozen Sections: 1-2 μg/mL (1/200-1/400). Immunohistochemistry on Paraffin Sections: 8 μg/mL (1/50). Proteinase K pretreatment forantigen retrieval is recommended. Suggested Positive Control: Human placenta. Has been described to work in FACS. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

CD31, also known as platelet endothelial cell adhesion molecule 1 (PECAM1), is a type I integral membrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. It is constitutively expressed on the surface of endothelial cells, and concentrated at the junction between them. It is also weakly expressed on many peripheral lymphoid cells and platelets. CD31 has been used to measure angiogenesis in association with tumor recurrence. Other studies have also indicated that CD31 and CD34 can be used as markers for myeloid progenitor cells and recognize different subsets of myeloid leukemia infiltrates (granular sarcomas). The CD31 antigen is found on cells lining and within the vasculature, and plays a role in the adhesive interaction between adjacent endothelial cells as well as between leukocytes and endothelial cells.Synonyms: End °CAM, GPIIA', PECAM-1, Platelet endothelial cell adhesion molecule
