Anti-FOSL1 Antibody

The Antibodies.com Anti-FOSL1 polyclonal reagent is a rabbit-host IgG preparation raised against FOS-like antigen 1, the AP-1 complex transcription factor implicated in epithelial-mesenchymal transition, osteoclast differentiation, and oncogenic reprogramming across several solid tumor types. Supplied as 100 µl of unconjugated antiserum applicable to western blot and immunofluorescence workflows, this Primary Antibodies reagent recognizes the FOSL1 protein in human, mouse, and rat samples. Researchers studying FRA-1 driven transcriptional programs in breast carcinoma, lung adenocarcinoma, glioblastoma, or rheumatoid synovial tissue commonly use it to monitor pathway activation and downstream target engagement. The polyclonal format increases the likelihood of recognizing multiple epitopes on the target protein, useful when investigating splice variants or post-translational modifications. The unconjugated format gives flexibility for downstream labelling with HRP, fluorophore, or biotin depending on the experimental read-out. Recommended storage at -20 °C in working aliquots preserves antibody activity through repeated freeze-thaw cycles. Shipped in a single-use vial, the reagent should be aliquoted on arrival to limit repeated freeze-thaw events. For research use only; not validated for diagnostic or therapeutic procedures.
