CD4+ T cells were sorted from mouse spleen, activated with anti-mouse CD3 and anti-mouse CD28, followed by culture in Th1-polarizing conditions, and re-activation with PMA and Ionomycin. Lysates from control (left) or PMA and Ionomycin-re-activated (right) cells were probed with purified eBio4B10 at 2 μg/ml, and revealed with HRP anti-mouse IgG.

Description

The eBio4B10 monoclonal antibody reacts with mouse and human T-bet. T-bet is a Th1-specific T-box transcription factor critical to the development of the Th1 CD4+ T cell lineage. This is known based on the observations that T-Bet deficient mice have impaired Th1 cell development, and that ectopic expression of T-Bet results in development skewed to the Th1 lineage. T-Bet expression is induced by the Th1 cytokine IFN-γ, and T-Bet also regulates the expression of IFN-γ, likely, at least in part, through the modification of DNA accessibility and histone remodeling. In addition to IFN-γ, T-Bet is also known to regulate the expression of IL-12Rβ and IL-2. Moreover, T-Bet plays a role in class-switch recombination in B-cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This eBio4B10 (4B10, 4-B10) antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and immunoblotting (WB).

Applications Tested

This eBio4B10 (4B10, 4-B10) antibody has been tested by western blot analysis of Th1-polarized mouse CD4+ T cells and can be used at 2 μg/ml as a starting dilution for western blotting.
