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:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
