Anti-JUNB (phospho S79) Antibody

This rabbit polyclonal antibody from Antibodies.com targets JUNB phosphorylated at serine 79, a modification linked to AP-1 transcription factor regulation downstream of cellular stress, cytokine, and growth factor signaling. The reagent is supplied as 100 µl of unconjugated IgG, allowing flexible pairing with secondary detection chemistries in immunohistochemistry (IHC) and immunofluorescence (IF) workflows. Cross-reactivity is established for Human, Mouse, and Rat samples, supporting comparative studies across standard model organisms and human tissue specimens. Researchers commonly apply the antibody to evaluate JUNB activation states in normal versus diseased contexts, including inflammatory, oncogenic, and developmental systems where AP-1-driven gene programs are implicated. For handling, keep refrigerated and protect from light, and avoid repeated freeze-thaw cycles when aliquoting working stocks for long-term use.
