Anti-STAT5a (Ab-694) Antibody

From Antibodies.com, this rabbit polyclonal reagent is raised against a synthetic peptide sequence surrounding residues 692–696 (D-G-Y-V-K) of human STAT5A and is affinity-purified using epitope-specific peptide chromatography to ensure selectivity for the endogenous target. The unconjugated IgG preparation detects total STAT5A protein and has been validated for Western blotting and immunohistochemistry in human, mouse, and rat samples. Supplied at 1.0 mg/mL in phosphate-buffered saline (pH 7.4) containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, the 50 µL aliquot is shipped at 4 °C and should be stored at –20 °C, with freeze/thaw cycles avoided to preserve activity. STAT5A (signal transducer and activator of transcription 5A) plays a central role in cytokine-driven signaling, and this reagent offers a reliable tool for researchers probing JAK/STAT pathway activation, mammary or hematopoietic lineage studies, and phosphorylation-state analyses across multiple model organisms.
