Radioligand binding to nAChR subunit chimeras expressed in  Drosophila  S2 cells. Cell surface [¹²⁵I]-α-bungarotoxin binding to transiently transfected Drosophila S2 cells with subunit chimeras (Dα5/5HT3A, Dα6/5HT3A and Dα7/5HT3A). Experiments were performed in triplicate and are means ± SEM of 4–14 independent experiments.
