Anti-AR (phospho S650) Antibody - Identical to Abcam (ab194866)

A rabbit polyclonal antibody raised against the androgen receptor (AR) phosphorylated at serine 650, supplied by Antibodies.com as an unconjugated IgG reagent in a 200 µl liquid format. Validated for immunohistochemistry (IHC) on human tissue, the antibody is referenced as identical to Abcam ab194866 and selectively detects AR only when the serine 650 residue is phosphorylated. Phosphorylation at this site modulates AR dimerization, DNA binding, and transcriptional activation, making this reagent useful for mapping androgen signaling in prostate, breast, and other hormone-responsive tissues. Recommended applications include staining of formalin-fixed paraffin-embedded sections and characterization of AR-dependent cell line models. For handling, store refrigerated and protect from light; aliquot to avoid repeated freeze-thaw cycles and preserve antibody activity across experiments.
