細胞ベースのレポーター遺伝子機能アッセイは、検証された細胞株を使用して実施する。細胞を播種し、完全培地で一晩インキュベートする。翌日、細胞を無血清培地(無血清Ham’s F12)で18〜24時間インキュベートする。OptiMEM培地中で、10μMのセロトニン及び化合物(1〜10μM)と共に細胞を4時間インキュベートすることにより、アッセイを実施する。細胞を収集し、リシスバッファーで溶解し、Perkin Elmer Victor Light Luminometerを使用してルシフェラーゼ活性を測定する。結合親和性(Kb)値を、光単位(発光量)として測定されたレポーター活性を用いて決定し、分析プログラムPrism 4(GraphPad software)で非線形回帰分析を用いて分析する。
