Anti-AR (phospho S213) Antibody

This rabbit polyclonal reagent from Antibodies.com selectively recognizes the androgen receptor only when phosphorylated at serine 213, a post-translational modification investigated in studies of androgen signaling, prostate cancer progression, and hormone-driven transcriptional regulation. Supplied as an unconjugated IgG in a 200 µl volume, the antibody is validated for Western blot (WB) and immunofluorescence (IF) workflows on human samples. Investigators working on castration-resistant prostate cancer, AR transactivation, kinase pathways that converge on S213, and ligand-dependent versus ligand-independent receptor activation use this reagent to monitor phospho-specific changes in cell and tissue lysates. The polyclonal format provides broader epitope coverage around the modified residue, supporting detection of low-abundance phosphorylated receptor. Storage recommendations and buffer composition are detailed on the accompanying product insert to preserve antibody activity across multiple freeze-thaw cycles.
