• Product nameAnti-FOXP3 antibody
    See all FOXP3 primary antibodies
  • Description
    Rabbit polyclonal to FOXP3
  • SpecificityThis antibody recognises a single clean band representing FOXP3 on HEK293 cell lysate overexpressing human FOXP3. This band is blocked by the immunising peptide and is not present in the control HEK293 cell lysate.
  • Tested applicationsSuitable for: WB, IHC-P, ICC/IF, ChIPmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Synthetic peptide conjugated to KLH derived from within residues 400 to the C-terminus of Human FOXP3.


  • Positive control
    • This antibody gave a positive signal in Hek 293 lysate over expressing human FOXP3

ICC/IF Use a concentration of 2 - 4 µg/ml.
ChIP Use at an assay dependent concentration.


  • FunctionProbable transcription factor. Plays a critical role in the control of immune response.
  • Involvement in diseaseDefects 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.
  • Sequence similaritiesContains 1 C2H2-type zinc finger.
    Contains 1 fork-head DNA-binding domain.
