Our CD47 (Extracellular region) Antibody mouse monoclonal primary antibody from PhosphoSolutions is produced in-house. It detects human CD47 (Extracellular region) Antibody and is Protein G purified. It is great for use in WB(Nat), ICC, IP.
Native western blot of human BEAS-2B lung cells (lane 1), NCI-H446 lung cancer cells (lane 2), lung mesothelioma cells: NCI-H28 (lane 3), and NCI-H2052 (lane 4). The blot was probed with mouse monoclonal anti-CD47 (CM0541) at 1:500.
CD47 is a five-pass transmembrane protein expressed on all normal cells, as well as in cancer cells. CD47 is used by macrophages to distinguish between "self" and "non-self" cells. SIRPα expressed on myeloid cells including macrophages, and neuronal cells in the central nervous system, can bind CD47. SIRPα cytoplasmic tail can inhibit macrophage phagocytosis towards CD47-expressing cells. Thus, the CD47/SIRPα pathway serves as an innate immune checkpoint. Additionally, CD47 was reported to modulate lymphocyte cell activation and proliferation. CD47 is over-expressed in many types of cancer, and the expression level of CD47 on cancer cells is negatively associated with cancer survival. Monoclonal antibody therapies that can block CD47-SIRPα interaction are being actively pursued for clinical applications. In addition to SIRPα, CD47 interacts with thrombospondin-1, VEGFR2, FAS, and certain integrins in different contexts, and influences their downstream signaling.

Clone M054 mouse monoclonal antibody detects native human CD47, as well as aldehyde-fixed CD47. The antibody works for staining in immunocytochemistry, capture and detection in ELISA, native immunoprecipitation and western blot. The antibody detects a 45 to 55 kDa band in native western blots of A431, BEAS-2B, MCF7, NCI-H446, NCI-H28, and NCI-H2052 cell lines.
