Anti-JUND (phospho S255) Antibody

Antibodies.com offers a rabbit polyclonal IgG antibody specific for JUND phosphorylated at serine 255, supplied as an unconjugated reagent in a 50 µL volume. The reagent is validated for Western blot and immunohistochemistry applications, enabling detection of phospho-S255 JUND in cell lysates and formalin-fixed tissue sections derived from human, mouse, and rat samples. As a member of the JUN family of AP-1 transcription factors, JUND contributes to the regulation of gene expression programs tied to proliferation, differentiation, and cellular stress responses, and serine 255 phosphorylation has been reported to modulate its dimerization behavior and DNA-binding activity. The polyclonal format provides recognition of multiple epitopes surrounding the phospho-serine target, which can be useful when probing this modification across different protein contexts. Storage at -20 °C in small aliquots is recommended to limit repeated freeze-thaw cycles and preserve binding activity. Intended for research use only.
