摘要
Fluorescence lifetime imaging(FLIM)is increasingly used to read out cellular autofluorescenceoriginating from the coenzyme NADH in the context of investigating cell metabolic state.Wepresent here an automated multiwell plate reading FLIM microscope optimized for UV illumi-nation with the goal of extending high content fluorescence lifetime asays to readouts ofmetabolism,We demonstrate its application to automated cellular autofluorescence lifetime imaging and discuss the key practical issues associated with its implementation.In particular,weillustrate its capability to read out the NADH-lifetime response of cells to metabolic modulators,thereby illustrating the potential of the instrument for cytotoxicity studies,assays for drugdiscovery and stratified medicine.
