Background

T-box expressed in T cells (T-bet), also known as T-box transcription factor TBX21, is a 62 kDa member of the T-box family of transcription factors and the Tbr1 subfamily. Human T-bet is 535 amino acids in length and contains a T-box DNA binding domain (aa 136-327). Human T-bet shares 88% aa sequence identity with mouse T-bet. T-bet is a nuclear protein highly apparent in Th1 cells. Northern blot analysis revealed that it is also expressed in lung, thymus and spleen. Functionally, T-bet controls the expression of the Th1 cytokine, IFN-gamma, and initiates Th1 lineage development from naïve Th precursor cells by both activating Th1 genetic programs and by repressing the opposing Th2 programs.

FAQs for T-bet/TBX21 Antibody (FAB53851R). (Showing 1 - 1 of 1 FAQ).

1. Do you make a Tbx21 ab for FACS for porcine?
   • We have not tested our Tbx21 antibodies for porcine, however you might like to test NBP1-43298 as part of our Innovators Reward Program. This is gained from testing a product on a species or application that we have not yet tested. I have carried out a blast to check the % homology between the pig protein and human protein, this is 94% and our lab recommends use if the % homology is 85% or above.
