合成生物學的其中一個目標在於利用已定義的基因元件組合成可作用的生物性系統。在本研究中，我們利用生物元件組裝出一個可調整型的生物性放大器，將其放入大腸桿菌內，並使用酵素免疫分析儀 (ELISA reader) 偵測其表現。
放大器內部元件的啓動子(promoters)與核醣體結合位點(ribosome binding sites)是從有良好定義的相關資料庫中所選取，並且選擇綠螢光蛋白(GFP)做為此基因電路實驗的報導蛋白。可調整型放大器的主要功用是調整誘導物IPTG和誘導物aTc來達到控制報導蛋白的最終生產濃度，其中IPTG的濃度是作為生物放大基因電路的輸入訊號，而aTc則是用於調整基因電路的放大倍率。藉由完整的線性方程式，我們能更準確的預測最終輸出迴路之綠螢光蛋白的放大倍率和綠螢光蛋白的濃度。這樣的生物性放大器未來可提供一個關於控制蛋白疫苗定量生產的功能。
