Anti-Fra-2 Antibody

Raised in rabbit against the Fos-related antigen Fra-2 (FOSL2), this unconjugated polyclonal antibody from Antibodies.com targets a transcription factor component of the AP-1 complex implicated in cell proliferation, differentiation, and inflammatory signaling. The reagent is supplied as a 100 µl volume and is validated for western blot (WB) and immunohistochemistry (IHC) workflows on human, mouse, and rat samples. Researchers studying oncogenic transformation, pulmonary fibrosis, cytokine regulation, or osteoclast differentiation frequently use Fra-2 antibodies to probe AP-1-dependent transcriptional programs in tissue sections and lysates. Because the antibody is unconjugated, it pairs cleanly with HRP- or fluorophore-coupled secondary reagents of the user's choice, and the polyclonal format increases the likelihood of recognizing multiple epitopes on the target protein. Aliquoting upon first use is recommended to limit freeze-thaw cycles; for short-term storage keep the vial refrigerated at 4°C, and for longer-term storage freeze at -20°C in working aliquots to preserve activity. Each lot is quality-controlled to confirm specificity for the Fra-2 protein, supporting reproducible detection across the indicated species.
