fluorometric

7-Ethoxyresorufin (Resorufin ethyl ether) (7-ER) is a fluorometric substrate and competitive inhibitor of cytochrome P450, particularly CYP1A1.

Calcein (Fluorexon) is a fluorescent dye and self-quenching probe used as an indicator of lipid vesicle leakage, a complexometric indicator for titration of calcium ions with EDTA, and for the fluorometric determination of calcium.

2,3-Diaminonaphthalene is a highly selective fluorometric and colorimetric reagent for selenium detection, and it is also used for the fluorometric determination of nitrite.

fluorometric substrate of cytochrome P450

fluorometric cytochrome P450 substrate

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).

Ac-YVAD-AFC is a fluorescent peptide substrate used to detect caspase-1. When cleaved, it releases the fluorescent molecule AFC, with an excitation wavelength of 400 nm and an emission wavelength of 505 nm.

N-(9-Acridinyl)maleimide is a maleimide-type fluorescent thiol probe that emits blue fluorescence upon thiol conjugation, with an excitation wavelength of 355 nm and emission wavelength of 465 nm. It can be used for detecting cysteine and glutathione.

1,2-Diamino-3,4-ethylenedioxybenzene functions as a carbonyl-reactive fluorometric labeling agent.
