Ac-DNLD-AMC is a fluorogenic caspase-3 substrate. Upon enzymatic cleavage by caspase-3, 7-amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify caspase-3 activity. AMC displays excitation emission maxima of 340-360 and 440-460 nm, respectively.
C-Laurdan, a fluorescent probe for imaging lipid rafts with environmentally sensitive fluorescence, exhibits strong photostability under two-photon excitation and is suitable for single and two-photon fluorescence imaging to detect lipid membrane properties such as membrane lateral organization and various membrane-associated processes [1].
7-Hydroxycoumarin-3-carboxylic acid, SE is the amine-reactive succinimidyl ester of 7-Hydroxycoumarin-3-carboxylic acid. This coumarin is also increasingly used to label peptides, nucleotides and carbohydrates.
