CD273, also known as B7-DC and Programmed Death Ligand 2 (PD-L2), is a 42kD member of the immunoglobulin receptor superfamily, and is a ligand for CD279 (PD-1). CD273 is primarily expressed on dendritic cells, and its expression can be induced on inflammatory macrophages when activated by interleukin 4 or Th2 cells. CD273 functions to inhibit T-cell proliferation by blocking cell cycle progression and cytokine production, and is particularly important in the maintenance of self tolerance.
Applications:
Suitable for use in Flow Cytometry and Immunohistochemistry (frozen). Other applications not tested.
Recommended Dilution:
Flow Cytometry: 1:10-1:50; 10ul labels 10e6 cells in 100ul
Optimal dilutions to be determined by the researcher.
Hybridoma:
P3U1 myeloma cells with spleen cells from immunized mice.
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.
