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 fluorometric peptide substrate of caspase-1, featuring an excitation wavelength (λ excitation) of 400 nm and an emission wavelength (λ emission) of 505 nm [1] [2].

N-(9-Acridinyl)maleimide, a maleimide-type fluorescent thiol reagent, exhibits negligible inherent fluorescence; however, its conjugates with thiol compounds display pronounced blue fluorescence. This characteristic enables its use in the fluorometric analysis of cysteine and glutathione [1].

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