  • 機能
    Probable transcription factor. Plays a critical role in the control of immune response.
  • 関連疾患
    Defects in FOXP3 are the cause of immunodeficiency polyendocrinopathy, enteropathy, X-linked syndrome (IPEX) [MIM:304790]; also known as X-linked autoimmunity-immunodeficiency syndrome. IPEX is characterized by neonatal onset insulin-dependent diabetes mellitus, infections, secretory diarrhea, trombocytopenia, anemia and eczema. It is usually lethal in infancy.

Anti-FOXP3 antibody [236A/E7] 画像

  • All lanes : Anti-FOXP3 antibody [236A/E7] (ab20034) at 5 µg/ml

    Lane 1 : Human thymus
    Lane 2 : Mouse thymus
    Lane 3 : Rat thymus

    Lysates/proteins at 20 µg per lane.

    Secondary
    IR-labelled goat anti-mouse (green; 800) at 1/10000 dilution

    Performed under reducing conditions.

    Predicted band size : 47 kDa
    Observed band size : 26,50 kDa (why is the actual band size different from the predicted?)

    This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with Anti-FOXP3 antibody [236A/E7] (ab20034; 5 microgram per mL), overnight at 4°C. Antibody binding was detected using infrared labelled goat anti-mouse (green; 1:10000) for 1 hour at room temperature before imaging.

  • IHC image of Foxp3 staining in Human normal tonsil formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab20034, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Performed under reducing conditions.

    Predicted band size : 47 kDa

    ab20034 detects Human FOXP3 protein at ~50 kDa in HEK293T cells overexpressing the protein. It also detects FOXP3 in Human tonsil tissue lysate, however this band is significantly weaker in endogenous conditions. Upon higher exposure, weak bands can also be observed in HEK293T cell lysate.

    This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with Anti-FOXP3 antibody [236A/E7] (ab20034; 5 microgram per mL) overnight at 4°C. Antibody binding was detected using infrared labelled goat anti-mouse (green; 1:10000) for 1 hour at room temperature before imaging.

  • ab20034 staining FOXP3 in Cynomolgus Monkey Spleen tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 10% donkey serum for 20 minutes at room temperature; antigen retrieval was by heat mediation using EDTA, pH9.0. Samples were incubated with primary antibody (1/100) for 30 minutes. A Biotin-conjugated Donkey anti-mouse polyclonal (1/2000) was used as the secondary antibody.

  • ab20034 staining FOXP3 in Human breast cancer tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with acetone/methanol (1:2), permeabilized with TBS-TritonX-100 and blocked with 10% serum for 10 minutes at 20°C. Samples were incubated with primary antibody (1/50 in PBT (PBS/BSA/Tween)) for 30 minutes at 20°C. An undiluted HRP-conjugated rat anti-mouse/rabbit IgG polyclonal was used as the secondary antibody.
