Trichinella spiralis, an intracellular parasitic nematode, can cause severe foodborne zoonosis, trichinellosis. The life cycle of T. spiralis consists of adult (Ad), muscle larvae (ML) and newborn larvae (NBL). The protein profiles in different developmental stages of the parasite remain

Selective modification of native proteins in live cells is one of the central challenges in recent chemical biology. As a unique bioorthogonal approach, ligand-directed chemistry recently emerged, but the slow kinetics limits its scope. Here we successfully overcome this obstacle
