Real-time monitoring of caspase-3/8 activity by self-assembling nanofiber probes in living cells†
Abstract
Caspase-3/8 are key members of the cysteine–aspartyl protease family with pivotal roles in apoptosis. We have designed and synthesized self-assembling probes, Nap-GFFpYDEVD-AFC and Nap-GFFpYIETD-AFC, with fluorescence ‘turn-on’ properties for real-time monitoring of Caspase-3/8 activity in living cells.
