Enzyme Activity Probes & Substrates

Browse substrates and optical reporter reagents for enzyme-activity assays. Enzyme-activated fluorogenic probes can convert a chemical transformation into a fluorescence readout.[1] Choose the exact reagent for your enzyme, sample and detection method, and distinguish fluorescent from color-based readouts. This collection does not imply that every substrate is selective for one enzyme or suitable for use in living cells.

    7-Acetoxy-1-methylquinolinium iodide

    Synonyms: AMQI

    7-Acetoxy-1-methylquinolinium iodide is a fluorogenic substrate specifically targeting cholinesterase. Upon hydrolysis, it emits fluorescence at 410 nm when excited at 320 nm, facilitating the detection and identification of cholinesterase inhibitors. This compound is widely utilized in fluorometric assays, contributing significantly to biochemical research and drug discovery efforts focused on cholinergic pathways.
