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

Phospho-specific antibody targeting the androgen receptor at serine 650, raised in rabbit and validated for immunohistochemistry on human tissue sections. Equivalent in sequence to the Abcam reference ab194866, this polyclonal IgG reagent from Antibodies.com detects the kinase-phosphorylated form of AR associated with ligand-driven nuclear translocation and transcriptional activation. Investigators studying prostate cancer progression, castration-resistant disease, or androgen signaling commonly apply the antibody to formalin-fixed paraffin-embedded specimens, where phospho-S650 staining patterns reflect receptor activation status in tumor and stromal compartments. Supplied as 50 µl of unconjugated antibody suitable for chromogenic or fluorescence IHC workflows, with the rabbit host minimizing endogenous background on human sections. Intended for research use only.
