MitoSOX Red 是一种具有特异性和细胞膜渗透性且靶向活细胞线粒体的新型荧光探针。MitoSOX Red 进入线粒体后会被超氧化物氧化,而不会被其他 ROS 或 RNS 生成系统氧化。MitoSOX Red 随后与线粒体内核酸结合,产生强红色荧光。MitoSOX Red 可以作为荧光指示剂,特异性检测超氧化物。超氧化物歧化酶 (Superoxide dismutase,SOD) 能够预防 MitoSOX Red 氧化。
Resorufin benzyl ether is a fluorometric probe that acts as a substrate for cytochrome P450 (CYP)3A4. It is typically used near its apparent Km value of 30 μM to screen the inhibition/activation potential of test compounds, to predict potential drug-drug interactions, or to monitor other CYP450 activities. Upon enzyme cleavage, resorufin benzyl ether generates a red fluorescent product (ex. 571 nm/em. 585 nm).
RB-OPD, also known as NO-red, is a fluorescent probe that combines o-phenylenediamine (OPD) and rhodamine nitric oxide (NO). With a λex of 550 nm and a λem of 590 nm, it exhibits exceptional sensitivity and selectivity.
