生物應(yīng)用
該重組螢火蟲熒光素酶是從來自北美螢火蟲（Photinus pyralis）的克隆基因表達的酶，其提供使用生物發(fā)光試劑檢測ATP或熒光素底物進行研究或生產(chǎn)試劑盒所需的可靠性和可靠性。 該重組酶可以潛在地消除可能在從天然來源純化的熒光素酶中發(fā)現(xiàn)的季節(jié)性和區(qū)域變異性的可能性。
該酶與熒光素，ATP和O2的反應(yīng)導(dǎo)致光的發(fā)射。 熒光素酶可用于檢測痕量的ATP。 螢火蟲熒光素酶也是基因表達研究中*常用的報告基因之一。 熒光素酶催化的生物發(fā)光反應(yīng)是測量基因表達的*靈敏的分析工具之一。 通過使用0.2μg熒光素酶可以檢測小于或等于1飛摩爾的ATP。
