CD47, also known as integrin-associated protein, is a 50kD glycoprotein expressed on all hematopoietic cell lines, epithelial cells, endothelial cells, fibroblasts and many tumor cell lines.
CD47 is involved in several cellular processes including regulation of T cell and dendritic cell activation, regulation of neutrophil (PMN) chemotaxis, caspase-independent apoptosis, and may act as a signal transducer in the regulation of cation fluxes across cell membranes. CD47 has been identified as a ligand for the inhibitory macrophage receptor known as signal regulatory protein alpha (SIRPalpha) and as a receptor for thrombospondin-1.
Applications:
Suitable for use in Flow Cytometry, Functional Assays, Immunohistochemistry (frozen), and Immunoprecipitation. Other applications not tested.
Recommended Dilution:
Flow Cytometry: 1:25-1:100; 10ul labels 10e6 cells in 100ul
Optimal dilutions to be determined by the researcher.
Hybridoma:
NS-1 myeloma cells with spleen cells from Balb/c 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, 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.
