一般描述
腔肠素是萤光素分子，可被多种萤光素酶利用，如 海肾属、刺虾属 和绿叶水母中存在的荧光素酶。
应用
天然腔肠素用于：
- 水母发光蛋白测定
- 在 COS-7 细胞中使用水母发光蛋白测量离子霉素或 PMA 诱导的细胞内钙离子浓度
- 在生物发光成像中分析病毒依赖性荧光素酶活性的存在
生化/生理作用
当 Ca 2 + 与复合物结合时，水母发光蛋白复合物的发光基团被氧气氧化并在 465 nm 处发光；用于测量细胞内 Ca 2 + 浓度，灵敏度高，动态范围大。
注意
避免光照

Identifying protein-protein interactions (PPIs) is essential for understanding various disease mechanisms and developing new therapeutic approaches. Current methods for assaying cellular intermolecular interactions are mainly used for cells in culture and have limited use for the noninvasive assessment of small
