    AMC Arachidonoyl Amide

    AMC-AA; 7-Amino-4-methyl coumarin-arachidonamide

    		 Endogenous Metabolite Metabolic Disease
    AMC arachidonoyl amide (AMC-AA) is one of several fatty acid amides which can be used to measure fatty acid amide hydrolase (FAAH) activity.1 FAAH is a relatively unselective enzyme in that it accepts a variety of amide head groups other than the ethanolamine of its nominal endogenous substrate anandamide.2 Exposure of AMC-AA to FAAH activity results in the release of the fluorescent aminomethyl coumarin that absorbs at 360 nm and emits at 465 nm. This allows the fast and convenient measurement of FAAH activity using a simple cuvette or microplate fluorometer.

    DiSBAC10

    		Fluorescent Dye Others
    DiSBAC10 is a voltage-sensitive fluorescent probe used to study cell membrane electrical activity in FRET assays. In a resting polarized cell, DiSBAC10 resides on the outer leaflet of the membrane where it accepts photons from excited fluorescein-labeled proteins and re-emits the photons at a higher wavelength. Depolarization of the cell causes rapid translocation of DiSBAC10 to the inner leaflet of the membrane, thereby increasing the distance between fluorophores and reducing the FRET signal.

    RADA

    		Bacterial Infection
    RADA is a fluorescent D-amino acid (FDAA) with high photostability and thermostability, which emits yellow-to-orange fluorescence. RADA shows low outer membrane permeability in wild-type Gram-negative Escherichia coli, but it targets penicillin-binding proteins and L,D-transpeptidases, mimics the interaction between acyl acceptors and enzyme intermediates, and integrates into peptidoglycan during biosynthesis. As a peptidoglycan labeling reagent, RADA metabolically integrates into the nascent peptidoglycan of live bacterial cells, labels the peptidoglycan at the poles and lateral walls of mycobacteria, and enables visualization of peptidoglycan synthesis and remodeling processes. RADA serves as a non-specific stain for fixed cells, is non-toxic to bacterial cells, and its red-shifted excitation/emission spectra reduce phototoxicity. RADA also supports virtual pulse-chase labeling experiments and stochastic optical reconstruction microscopy for sub-diffraction-limited imaging of bacterial cell walls .
