See IHC antigen retrieval protocols.


  • Function
    Transcription factor that controls the expression of the TH1 cytokine, interferon-gamma. Initiates TH1 lineage development from naive TH precursor cells both by activating TH1 genetic programs and by repressing the opposing TH2 programs.
  • Tissue specificity
    T-cell specific.
  • Involvement in disease
    Genetic variations in TBX21 are associated with susceptibility to asthma with nasal polyps and aspirin intolerance (ANPAI) [MIM:208550]. A condition consisting of asthma, aspirin sensitivity and nasal polyposis. Nasal polyposis is due to chronic inflammation of the paranasal sinus mucosa, leading to protrusion of edematous polyps into the nasal cavities.

We did test the antibody for western blotting, but it tested negative. The blot was blank on Jurkat, HuT-78 and Molt-4 lysates.
