Add. information This antibody was produced serum-free, without fetal calf serum.
Application Immunohistochemistry on Frozen Sections: 0.25-0.5 µg/ml (1/400-1/800). 
Immunohistochemistry on Paraffin Sections: 20 µg/ml (1/10). 
Proteinase K pre-treatment for antigen retrieval is recommended. Do not use standard 4% Formalin fixation, but max. 0.05% glutaraldehyde or 1% paraformaldehyde!
Suggested Positive Control: Mouse spleen.
Has been described to work in FACS.
Background 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).

Monoclonal CD31 antibody (clone ER-MP12) recognizes PECAM-1, platelet/endothelial cell adhesion molecule 1.
It is a general marker for the detection of a major population of haematopoietic stem cells and is useful for the accumulation of early murine macrophage precursors from bone marrow cell suspensions by FACS. An even more precise characterization of such isolated and concentrated precursor cells is achieved when ER-MP12 is combined with other markers like ER-MP20 (anti Ly-6C, Cat.-No BM4019) or ER-MP58 (Cat.-No BM4089).
The ER-MP12 antigen is also expressed by endothelial cells.
Antigen Distribution 
Isolated Cells: The antigen is found on the surface of approximately 40% of freshly isolated bone marrow cells of adult mice, on the majority of immortalized macrophage precursor cell lines (M1, RMB-1, RMB-3) corresponding to CFU-GM cells. The antibody detects pluri- and multipotent stem cells and prothymocytes as well as particular lymphoid cells in bone marrow and peripheral lymphoid organs.
Tissue Sections: The antigen is detected within the lymphopoietic islands in the spleen of newborn (day 12) and in the bone marrow of adult mice. Capillary endothelial cells of adult mice also express the antigen.
Detects a major population of Mouse colony forming unit macrophage (CFU-M) precursor cells, subpopulation of pre CFU-M and monoblasts, precursor cells of granulocytes.
