Anti-STAT1 (Phospho-Tyr701)

Y011044 is a rabbit polyclonal antibody specific for STAT1 phosphorylated at Tyrosine 701, the JAK kinase-mediated activating modification that enables STAT1 dimerization, nuclear translocation, and interferon-stimulated gene (ISG) transcription. Validated for WB at 1:500–1:2,000 and IHC at 1:50–1:300, Y011044 detects active pTyr701-STAT1 at ~91 kDa in human and mouse samples.
