Human ER alpha/NR3A1 PharmaGenie ELISA Kit (SBRS0541)

This quantitative immunoassay from Assay Genie targets human estrogen receptor alpha (ESR1/NR3A1), a ligand-activated nuclear transcription factor that mediates estrogen signaling. The 96-assay kit supports measurement in cell culture supernatant, plasma, and serum specimens, making it relevant to translational research on hormone-responsive breast cancer models, endometrial biology, and osteoporosis. Researchers apply the kit for in vitro profiling of receptor abundance in estrogen-treated cell lines and for characterizing clinical cohorts where ERα status guides therapeutic decisions. Each pack includes a pre-coated microplate and reagents sufficient for the stated number of determinations, intended for research use only in laboratory settings.
