Anti-Fos Antibody

This polyclonal reagent from Antibodies.com targets Fos (c-Fos), an immediate-early gene product that dimerizes with Jun family partners to form the AP-1 transcription factor complex implicated in cell proliferation, differentiation, and stimulus-response signaling. The antibody is raised in rabbit and validated for Western blot and immunohistochemistry applications across human, mouse, and rat specimens, supporting signal-transduction, oncology, and neuroscience workflows where rapid transcriptional activation is being characterized. Supplied as a 100 µl aliquot in unconjugated format, the reagent pairs with standard HRP- or fluorophore-conjugated secondary antibodies, allowing laboratories to tailor detection chemistry to their preferred protocol.
