荧光素酶发光原理?
利用荧光素酶与底物结合发生化学发光反,应的特点,把感兴趣的基因转录的调控元件克隆在萤火虫荧光素酶基因(fireflyluciferase)的. 上游,构建成荧光素酶报告质粒。
然后转染细胞,适当刺激或处理后裂解细胞,测定荧光素酶活性。通过荧光素酶活性的高低判断性刺前后或不同刺激对感兴趣的调控元件的影响。
同时,为了减少内在的变化因素对实验准确性的影响,将带有海肾荧光素酶基因(Rinilla luciferase)的质粒作为对照质粒与报告基因质粒共转染细胞,提供转录活力的内对照,使测试结果不受实验条件变化的干扰。
荧光素酶发光原理?
萤火虫荧光素酶在氧气、ATP和镁离子同时存在的条件下,催化荧光素氧化,生成氧化荧光素,同时产生黄绿色光,波长540-600nm。
荧光素酶(luciferase)是自然界中能够产生生物荧光的酶的总称。荧光素酶可以催化荧光素氧化成氧化荧光素,在荧光素氧化的过程中,会发出生物荧光。然后可以通过荧光测定仪测定荧光素氧化过程中释放的生物荧光。荧光素和荧光素酶这一生物发光体系,可以极其灵敏、高效地检测基因的表达,是检测转录因子与目的基因启动子区DNA相互作用的一种检测方法。
目前,最有代表性的是从甲虫中分离得到的萤火虫荧光素酶(Firefly luciferase)和从海肾中分离得到的海肾荧光素酶(Renilla luciferase)。
