    Product Information

    Product Usage Information

    This product is the carrier free version of product #36096. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

    This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

    BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

    Formulation

    Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

    For standard formulation of this product see product #36096

    Storage

    Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

    Specificity / Sensitivity

    CD47 (E2V9V) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total CD47 protein.

    Species Reactivity:

    Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with mouse CD47 recombinant protein.

    Background

    CD47 is a five-pass transmembrane protein expressed on all normal cells. It binds to the SIRPα that is expressed on myeloid cells, including macrophages, and neuronal cells in the central nervous system. Binding of CD47 to SIRPα promotes phosphorylation of tyrosine residues in the immunoreceptor tyrosine-based inhibitory motifs (ITIMs) within the SIRPα cytoplasmic tail, inhibiting macrophage phagocytosis toward CD47-expressing cells. In this way, CD47 serves as a "don't eat me" signal or a marker of "self", functioning as an innate immune checkpoint. Additionally, CD47 was reported to modulate lymphocyte cell activation and proliferation (1-3). CD47 is overexpressed in many types of cancer. The expression level of CD47 on cancer cells is negatively associated with the response to therapies, and low expression on tumor cells is associated with a better prognosis and survival. Reagents that can block CD47-SIRPα interaction are being actively pursued for therapeutic applications (4,5). In addition to SIRPα, other proteins have been reported to bind to CD47. Thrombospondin-1 (TSP1) competes with SIRPα to bind to CD47 in the extracellular region and activates signaling pathways downstream of CD47 (6). CD47 can laterally associate with VEGFR2, FAS, and certain integrins in different contexts, and influences their downstream signaling (7-9). CD47 can be shed from the cell surface by proteolytic cleavage. In addition, CD47 is present on extracellular vesicles including exosomes, suggesting additional extracellular signaling potential (10).
