Anti-JUN (phospho S243) Antibody

Phosphorylation of the c-Jun transcription factor at serine 243 is a regulatory modification controlled by JNK-family kinases and is linked to altered activity of the AP-1 complex in stress, mitogenic, and oncogenic signalling. This unconjugated rabbit polyclonal IgG reagent from Antibodies.com recognises the phosphorylated S243 epitope on human c-Jun and is validated for western blot detection of the target in cell and tissue lysates. Supplied as 200 µl of antiserum in a single-use vial, the antibody can be paired with standard HRP- or fluorophore-conjugated secondary antibodies for chemiluminescent or fluorescent visualisation on PVDF or nitrocellulose membranes. Researchers studying MAPK/JNK cascades, transcription factor regulation, or phospho-proteomic responses can use this reagent to monitor activation-state changes of c-Jun across time-course and stimulation experiments. For research use only.
