Intracellular Flow Cytometry
Mouse IgG1, κ
Yeast-expressed, recombinant mouse GM-CSF


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.


Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).

Recommended Usage

Each lot of this antibody is quality control tested by intracellular flow cytometry using our True-Phos™ Perm Buffer in Cell Suspensions Protocol. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.

* PerCP/Cyanine5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.
