Lymphocyte antigen 6C2, MACROPHAGE PRECURSOR CELLS (Ly-6c)

The antigen is a 14kD surface protein which is very similar to Ly-6C and may be analogous to human CD59. It is inducible by IFN-alpha, IFN-beta and IFN-gamma. In tissue sections, the antigen is found on macrophage precursor subpopulations. In the bone marrow and hemopoietic islands of the lymphoid organs, and in the spleen. Activated macrophages in inflammatory tissues also express the related antigen. The monoclonal antibody also identifies activated macrophages in inflammatory tissues where the simultaneous use of the murine pan-macrophage marker BM8 (anti-F4/80) is recommended. In combination with an anti-mouse CD31/PECAM-1 antibody, can be used to evaluate the cellular composition in murine bone marrow (e.g. using flow cytometric analysis). Also detects a wide range of endothelial cells. \n\nApplications:\nSuitable for use in Flow Cytometry and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nFlow Cytometry: 1:50\nImmunohistochemistry: 1:50\nThe antigen is glutaraldehyde (0.05%) and paraformaldehyde (1%) resistant. \nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, 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.
