Time-gated luminescence microscopy with responsive nonmetal probes for mapping activity of protein kinases in living cells†
Abstract
A photoluminescence probe ARC-1185, possessing both high affinity towards basophilic protein kinases (PKs) and microsecond-scale luminescence lifetime when associated with a kinase, was used for the mapping of ARC-1185–PK complexes in living cells with time-gated luminescence microscopy.
