Abstract
Herein, as a proof of concept, we developed the first enzymatic VIE fluorogenic probe for protein tyrosine phosphatase 1B (PTP1B). The detection and imaging of PTP1B using VIE in living cells were both realized. Particularly importantly, the designed probe herein provides a guideline and platform for the development of new VIE-based enzymatic probes.
