Estrogen-receptor binding assays measure how a compound such as enclomiphene binds the estrogen receptor and whether it acts as an agonist or antagonist in a given cell context. This guide outlines the methods.
Binding assays
Competitive binding assays measure a compound’s affinity for the estrogen receptor relative to a reference ligand. This quantifies how tightly enclomiphene engages the receptor.
Functional (reporter-gene) assays
Estrogen-response-element reporter assays reveal whether binding produces agonist or antagonist transcriptional activity in the cell model used — the defining SERM behavior.
Design and controls
Use ER-expressing cell lines, vehicle controls, a reference agonist/antagonist, and replicates. Concentration is expressed in molarity (EC50/IC50), never a dose.
