Figure 9

Competitive binding curve between ER/Fluormone ™ and increasing concentrations of E2 and Fen to ERα (A) and ERβ (B), after 4 h incubation period. A 100% polarization value corresponds to no competition, due to the absence of the competitor. Results represent the means ± SEM. of three separate experiments. ND, non-detectable.
