The rat CD200 cell surface antigen, also known as OX-2, is a type I membrane glycoprotein, expressed on rat thymocytes, neurons, follicular dendritic cells, endothelium and at low levels on some B cells and smooth muscle cells. Studies have indicated that the CD200-CD200 ligand system is important in the control of macrophage and granulocyte activation and that this antibody blocks OX-2 mediated T cell costimulation. Applications: Suitable for use in Flow Cytometry, Immunohistochemistry (frozen), and Immunoprecipitation. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:50-1:100, 10ul labels 10e6 cells in 100ul Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark.
