NPE-caged-proton

NPE-caged-proton is a reagent that releases protons under UV light and has the activity of activating the fusion protein GP64 under weak acidic conditions. NPE-caged-proton can promote the binding of enveloped viruses to liposome membranes with acidic phospholipids in an environment of pH 4.0 to 5.5, thereby initiating membrane fusion. The ultraviolet unblocking effect of NPE-caged-proton can lower the environmental pH, thereby triggering the process of viral membrane fusion. When studying the interaction between viruses and cell membranes, NPE-caged-proton provides a valuable tool for revealing the subtle behaviors of viruses in different chemical and biochemical environments[1].
