- Description
- Description: The monoclonal antibody TWAJ recognizes mouse and human Gata-3, a member of the Gata family of transcription factors. Gata-3 is a T cell-specific transcription factor important for thymic development and Th2 differentiation. Expression during embryonic development is found in the central nervous system, skin, mammary glands and kidney. During development, the expression of Gata-3 is essential as homozygous knock-out of Gata-3 is embryonic lethal. The Gata-3 is also essential for T cell commitment and survival. In the thymus, expression is found mainly on the CD4 single positive cells. During Th2 differentiation, Gata-3 binds to the IL-4 promoter as well as represses the expression of T-bet, thus inhibiting Th1 differentiation. Alternative splice variants have been reported especially in the MCF7 cell line. The TWAJ Human/Mouse Gata-3 antibody will recognize both forms (50 and 45 kDa) of the protein. Staining with the TWAJ Human/Mouse Gata-3 antibody requires the use of the Foxp3/Transcription Factor Staining Buffer Set.(Product # 00-5523-00) Crossreactivity in rhesus monkeys has been published. Applications Reported: This TWAJ antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This TWAJ antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of mouse thymocytes using the Foxp3/Transcription Factor Staining Buffer Set (Product # 00-5523) and protocol. Please refer to Best Protocols: Protocol B: One step protocol for (nuclear) intracellular proteins located under the Resources Tab online. This can be used at 5 µL (0.06 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488 nm; Emission: 710 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered.

Cells were first gated on HDAC3 + or HDAC3 - events, then gating for T h 1 (T-bet + ), T h 2 (GATA3 + ), T h 17 (RORgammat + ), T reg (Foxp3 + CD25 + ), and T fh (CXCR5 + PD-1 + Bcl-6 hi ) is shown (left). Bar plots on right represent pooled data for the total cell number +- standard deviation (SD) from three independent experiments ( n = 4-5 mice/group in total). Non-T fh CXCR5 - PD-1 - cells (dark gray histograms) were used as a negative control for Bcl-6 expression to set the gate on the Bcl-6 histograms. Statistical significance was determined for the indicated comparisons using ordinary one-way analysis of variance (ANOVA) with Tukey's multiple comparisons test (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001). Figure 2--figure supplement 1. Histone deacetylase 3 (HDAC3)-deficient T cells from dLck-Cre HDAC3 cKO mice have reduced differentiated T h -cell populations. Identification of helper T-cell populations in vivo. Lymphocytes were harvested from mesenteric lymph nodes of wild-type (WT) and dLck-Cre HDAC3 cKO mice, and labeled for flow cytometry. Cells were first gated on HDAC3 + or HDAC3 - events, then gating for T h 1 (T-bet + ), T h 2 (GATA3 + ), T h 17 (RORgammat + ),

- Extended Data Figure 7 Distinguishing the drivers of autoimmunity in the absence of T-bet + Treg cells a,b , ex-Treg cells are no more pathogenic than effector CD4 T cells. a , CD4 + CD25 + (Treg) cells were sorted from lymph nodes of Tbx21 RFP-Cre Foxp3 WT mice, and CD4 + CD25 - (effector) and CD4 + CD25 lo (exTreg) cells were sorted from lymph nodes of Tbx21 RFP-Cre Foxp3 FL mice for transfer into Tcrb - / - Tcrd - / - mice. Intracellular staining for Foxp3 demonstrates purity of cell populations. b , Weights of Tcrb - / - Tcrd - / - mice receiving CD4 + CD25 + (white squares), CD4 + CD25 - (black squares), and CD4 + CD25 lo (gray squares) cells. c , Percentages and numbers of the indicated T cell populations in spleens of mice analyzed on d62 post transfer. d,e , T-bet + effector alphabetaT cells drive disease upon ablation of T-bet + Treg cells. Lethally irradiated Tcrb - / - Tcrd - / - mice were reconstituted with a 1:1 mix of CD45.2 + Tbx21 RFP-Cre/WT R26 iDTR T-cell depleted bone marrow cells with either CD45.1 + Foxp3 KO , CD45.1 + Foxp3 WT , or CD45.2 + Tcrb KO T-cell depleted bone marrow cells. Mice were injected with 0.5mug diphtheria toxin (DT) on day 0, then treated daily with 0.1mug DT for 22 days before analysis. d , Weight loss in Tbx21 RFP-Cre/WT R26 iDTR :Foxp3 KO (red line) vs. Tbx21 RFP-Cre/WT R26 iDTR :Foxp3 WT (black line) vs. Tbx21 RFP-Cre/WT R26 iDTR :Tcrb KO (blue line) reconstituted mice. e , Representative fl

Dashed line indicates background fluorescence levels in non-reporter cells. d Flow cytometry plots showing Foxp3 and IL-10 expression by wildtype and Bach2 -/- CD4 T cells after Treg cell-inducing culture, and quantification (right). e Flow cytometry plots showing Foxp3 expression by wildtype, Bach2 -/- , Blimp1 fl/fl Lck Cre and Bach2 -/- Blimp1 fl/fl Lck Cre after three days culture in Treg cell-inducing conditions, and frequency of Foxp3 and IL-10 expressing cells (below). Flow cytometry plots are representative, data pooled from ( a ) or representative of two ( c - e ) or six ( b ) independent experiments. Statistical significance tested using two-way ANOVA with Tukey's test ( e ). Otherwise, significance was tested using the unpaired Student's t- test. Error bars denote mean +- S.D.
