3824005 25 µg $90.00       
3824010 100 µg $180.00       
Clone: 4B10
Isotype: Mouse IgG1, κ
Reactivity: Human, Mouse
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application:

WB, ICFC - Quality tested
IF, IP - Reported in the literature

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 True-Nuclear™ Transcription Factor Staining Protocol. For Western blotting, the suggested use is 1 to 2 ug per ml. 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.

Total cell lysate from PBMC

Total cell lysate from PBMC (lane 1, 15 µg) and PBMC treated with 5 µg/mL CD3 and 2 µg/mL CD28 (lane 2, 15 µg) were resolved by electrophoresis (4-12% Bis-Tris), transferred to nitrocellulose, and probed with purified anti-T-bet antibody (clone 4B10). Proteins were visualized using an HRP Goat anti-mouse IgG Antibody and chemiluminescence detection. Direct-Blot™ HRP anti-β-actin antibody (clone 2F1-1) was used as a loading control.

Human peripheral blood lymphocytes were

Human peripheral blood lymphocytes were surface stained with CD3 (clone OKT3) APC and then treated with True-Nuclear™ Transcription Factor Buffer Set. The cells were then stained with purified T-bet (clone 4B10) followed by anti-mouse IgG1 PE.



Description:

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.
