Anti-JUNB (phospho S79) Antibody

From Antibodies.com, this rabbit polyclonal reagent is raised against human JUNB and specifically detects the phosphorylated serine 79 epitope, a modification that controls JUNB's contribution to AP-1 transcription factor complexes. The unconjugated IgG antibody is supplied in a 200 µl volume and is validated for immunohistochemistry and immunofluorescence on human, mouse, and rat samples, making it a practical choice for comparative studies across model organisms. Because the reagent recognizes a phospho-specific site, researchers can distinguish signaling-active JUNB from total JUNB pools in tissue sections, which is useful when tracking downstream effects on cell proliferation, differentiation, and stress responses. The polyclonal format improves the chance of robust signal across varying fixation conditions encountered in IHC, while the unconjugated format gives laboratories flexibility to pair the antibody with their preferred fluorophore, chromogen, or secondary detection system for IF. For best results, aliquot on receipt and store at -20°C, avoiding repeated freeze-thaw cycles to preserve reagent activity over time.
