Total cell lysates (15 µg protein) from serum-starved HeLa S3 cells treated without (Lane 1) or with (Lane 2) 10 ng/mL human IFN-α2 (Cat. No. 592702) for 10 minutes were resolved by 8% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 2 µg/mL (1:250 dilution) purified anti-STAT1 Phospho (Tyr701) antibody (clone A17012A). Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse-IgG (Cat. No. 405301) at a 1:3000 dilution. Equal STAT1 loading was confirmed using a pan anti-STAT1 antibody that recognizes both STAT1 α (87 kD) and β (83 kD) isoforms. -

Human peripheral blood mononuclear cells were treated with (left), or without (right) Recombinant Human Interferon-γ (Cat No. 570204) for 15 minutes, fixed with Fixation Buffer (Cat. No. 420801), permeabilized with True-Phos™ Perm Buffer (Cat. No. 425401) then stained with CD4 (clone A161A1) APC and purified anti-STAT1 Phospho (Tyr701) (clone A17012A), followed by anti-mouse IgG PE. Data was gated on lymphocyte and monocyte populations. -
Human peripheral blood monocytes were treated with (filled histogram), or without (open histogram) Recombinant Human Interferon-γ (Cat. No. 570204) for 15 minutes, fixed with Fixation Buffer (Cat. No. 420801), permeabilized with True-Phos™ Perm Buffer (Cat. No. 425401) then stained with purified anti-STAT1 Phospho (Tyr701) (clone A17012A), followed by anti-mouse IgG PE. -
Serum starved HeLa cells were untreated (panel A) or stimulated with 100 ng/mL IFN-α2 (Cat. No. 592702, panel B) for 20 minutes, fixed with 4% paraformaldehyde for 10 minutes, permeabilized with ice-cold methanol for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with a 1:100 dilution (5 µg/mL) of purified anti-STAT1 Phospho (Tyr701) Antibody, clone A17012A, for two hours at room temperature, followed by incubation with Alexa Fluor® 594 goat anti-mouse IgG Antibody(Cat. No. 405326) at 2.0 µg/mL. Nuclei were counterstained with DAPI, and the image was captured with a 60X objective. -
Chromatin Immunoprecipitations (ChIP) were performed with cross-linked chromatin samples from 4 X 106 of HT1080 cells treated with IFNγ for 30 minutes with either A)1:50 dilution of Go-ChIP-Grade™ Purified anti-STAT1 Phospho (Tyr701) (Clone A17012A) or B) equal amount of Purified Mouse IgG1, κ Isotype Control Antibody (Clone MG1-45, Cat. No. 401401) by using Go-ChIP-Grade™ Protein G Enzymatic Kit (Cat. No. 699904). The enriched DNA was purified and quantified by real-time qPCR using primers targeting human TAP1 gene region and α-Satellite repeats. The amount of immunoprecipitated DNA in each sample is represented as signal relative to total amount of input chromatin.

STAT1, also known as signal transduction and activator of transcription 1, is a ubiquitously expressed cytoplasmic protein and is activated in response to cytokine signaling, including IFN-α, IFN-γ, EGF, PDGF, and IL-6. Upon activation, STAT1 is phosphorylated at Tyrosine 701 (Tyr701) by receptor-associated kinases, including JAK1, JAK2, and TYK2. This results in STAT1 dimerization and subsequent translocation to the nucleus, where it functions as a transcriptional activator. STAT1 is involved in IFN-mediated immune responses, and STAT1-deficient mice are highly sensitive to bacterial and viral infections.

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1 - 2.0 µg per ml (1:250-5000 dilution). For intracellular flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. For immunocytochemistry, a range of 5.0 μg/ml is recommended. For ChIP applications, the suggested dilution is 1:50 by volume. It is recommended that the reagent be titrated for optimal performance for each application.
For intracellular flow cytometry our True-Nuclear™ Transcription Factor Staining Protocol is recommended. - Application Notes
-
Clone A17012A recognizes STAT1 phosphorylated at Tyrosine 701 (Tyr701).
