Anti-STAT3 (Ab-727) Antibody

This rabbit polyclonal antibody targets STAT3, a transcription factor involved in cytokine signaling, cell growth regulation, and immune response pathways. Produced by Antibodies.com, the reagent is supplied as 100 µl of unconjugated antisera in a vial, ready for direct labeling or secondary detection workflows. Validated applications include Western blot and immunohistochemistry, supporting protein expression studies in human samples and tissue sections. The antibody recognizes the epitope around residue 727 of STAT3, allowing researchers to investigate baseline expression and signaling-related modifications of this transcription factor. As a polyclonal reagent raised in rabbit, it provides broader epitope coverage than monoclonal alternatives, which can be useful when probing STAT3 variants or post-translationally modified forms in cell lysates and fixed specimens. For research use only.
