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.
