Y011073 by MBP Inc. is a rabbit polyclonal antibody detecting Estrogen Receptor β (ESR2) phosphorylated at Ser167 — a growth factor signalling-associated phosphorylation site linked to ligand-independent receptor activation. Validated for WB, IHC, IF/ICC, and ELISA. Note: pSer167 is most extensively characterised on ERα; researchers should apply appropriate isoform-specificity controls. Research Use Only.
