CD4+ T cells were sorted from mouse spleen, cultured in either Th1- (left) or Th2- (right) polarizing conditions and restimulated with PMA and Ionomycin. Th1 or Th2 cells were then stained intracellularly, using the eBioscience Foxp3 Staining Buffer Set (cat. 00-5523), with 1.0 μg of Alexa Fluor® 647 Mouse IgG1, K Iso Cntrl (cat. 51-4714) (open histogram) or 1.0 μg of Alexa Fluor® 647 anti-mouse/human T-Bet (colored histogram). Total cells were used for analysis.

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 intracellular staining followed by flow cytometric analysis.

Applications Tested

This eBio4B10 (4B10, 4-B10) antibody has been tested by intracellular staining and flow cytometric analysis of Th1-polarized CD4+ T cells. This can be used at less than or equal to 2 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

For intracellular staining with the eBio4B10 monoclonal antibody, it is recommended to use the eBioscience Foxp3 Staining Buffer Set (cat. 00-5523).
