ICFC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation2 and immunofluorescence microscopy3.

NOTE: For flow cytometric staining with this clone, True-Nuclear™ Transcription Factor Buffer Set offers improved staining and is highly recommended over the Foxp3 Fix/Perm Buffer Set and the Nuclear Factor Fixation and Permeabilization Buffer Set .

Recommended Usage:

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining using our True-Nuclear™ Transcription Factor Staining Protocol. For flow cytometric staining, the suggested use of this reagent is 1.0 µg per million cells in a staining volume of 100 µl. It is recommended that the reagent be titrated for optimal performance for each application.

Human peripheral blood lymphocytes were

Human peripheral blood lymphocytes were surface stained with CD3 APC and then treated with True-Nuclear™ Transcription Factor Buffer Set (Cat# 424401). Cells were then stained with T-bet (clone 4B10) PE (top) or mouse IgG1, κ PE isotype control (bottom).


T-bet, also known as T-box transcription factor T-bet, is considered to be a "master regulator" of Th1 lymphoid development controlling the production of the cytokine IFN-γ. T-bet is widely expressed in hematopoietic cells including stem cells, NK cells, B cells, and T cells. T-bet is critical for the control of microbial pathogens, and knockout animals show multiple physiologic and inflammatory features characteristic of asthma. T-bet expression is optimally observed after IL-12 stimulation and can be suppressed by addition of the Th2 cytokine IL-4 or neutralization of IL-12.

Other Names: T-box expressed in T cells, T box 21, TBLYM
Structure: T-box transcription factor, approximately 58 kD.
Distribution: Nuclear; expressed in T cells, hematopoietic stem cells, NK cells, B cells, lung, spleen.
Function: Th1-specific T-box transcription factor controlling expression of the hallmark Th1 cytokine, interferon gamma (IFN-γ). T-bet expression is critical for the control of microbial pathogens.
