Our Abpromise guarantee covers the use of ab3283 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

アプリケーション Abreviews 特記事項
Flow Cyt Use at an assay dependent concentration.

ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.

Functional Studies Use at an assay dependent concentration.

This antibody blocks the binding of SIRP alpha (Yoshida, et al.; Latour et al.) and inhibits in assays where CD47-integrin association is required.

ICC Use at an assay dependent concentration.
IP Use at an assay dependent concentration. (native, with protein G): use at a concentration of 2µg / mg protein lysate.
ICC/IF Use at an assay dependent concentration. PubMed: 20923773
IHC-Fr Use at an assay dependent concentration. PubMed: 22451919
WB Use at an assay dependent concentration. Detects a band of approximately 49 kDa (predicted molecular weight: 35 kDa).


  • 機能Has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity). Receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation. May play a role in membrane transport and/or integrin dependent signal transduction. May prevent premature elimination of red blood cells. May be involved in membrane permeability changes induced following virus infection.
  • 組織特異性Very broadly distributed on normal adult tissues, as well as ovarian tumors, being especially abundant in some epithelia and the brain.
  • 配列類似性Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • 細胞内局在Cell membrane.

Anti-CD47 antibody [B6H12.2] 画像

  • ab3283 at 1µg/ml staining CD47 from human OVCA3 cells by ICC. The cells were methanol fixed, blocked with 3% serum and incubated with the primary antibody for 30 minutes. A biotinylated horse anti-mouse IgG was used as the secondary antibody.

  • ab3283 staining CD47 in HUVEC cells by Immunocytochemistry/ Immunofluorescence.
    The cells were fixed with 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.25% Triton X-100 for 5 minutes and blocked with 1% BSA in 0.1% Tween 20 and PBS for 1 hour at room temperature. The cells were incubated in a mixture of two primary antibodies ab3283 and a rabbit anti-human VEGFR2 overnight at 4 °C. The cells were then incubated with a mixture of two secondary antibodies (Alexa Fluor 488 anti-rabbit and Alexa Fluor 594 anti-mouse) in 1% BSA for 1 hour at room temperature in the dark. Counterstained with DAPI.
  • Overlay histogram showing peripheral blood lymphocytes stained with ab3283 (red line). The cells were incubated with the antibody (ab3283, 1µg/1x106 cells) for 30 min at 4ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H&L) (ab96879) at 1/200 dilution for 30 min at 4ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed gating on peripheral blood lymphocytes.

  • Anti-CD47 antibody [B6H12.2] (ab3283) at 1 µg/ml + Human brain tissue lysate - total protein (ab29466) at 10 µg

    Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 35 kDa
    Observed band size : 49 kDa (why is the actual band size different from the predicted?)

    Exposure time : 4 minutes
    CD47 contains an exstensive number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

Thank you for contacting Abcam.

As we discussed on the phone, the immunogen sequences for ab53444, ab9089, and ab3283 are unknown due to all 3 immunogens arising from tissue and cell preparations.

For CD47 (ab9089 and ab3283) the huma...

The antibody ab3283 is raised against full-length CD47 and the epitope the antibody recognizes has not been mapped, so there is no blocking peptide available. That is also the case for several other CD47 antibodi...
