Thioredoxin reductase (TrxR) enzymes are critical in regulating redox homeostasis in cells. We report the first two-photon fluorescent probe of mammalian TrxR (TP-TRFS). TP-TRFS retains high specificity in recognizing TrxR. More importantly, the two-photon absorbing character of TP-TRFS enables it t...
