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.Product Details

- Recommended Usage
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. 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).
When using this clone for ICC, we recommend using methanol to permeabilize fixed cells.
