Choosing Primary and Control Reporters for Dual-Luciferase Assays

Dual-Reporter Assays give scientists the ability to simultaneously measure two reporter enzymes within a single sample. In dual assays, the activity of an experimental reporter is correlated with the effect of specific experimental conditions, while the activity of a control reporter relays the baseline response, providing an essential internal control that reduces variability caused by differences in cell viability or transfection efficiency. The Nano-Glo® Dual-Luciferase® Reporter (NanoDLR™) Assay provides a choice of two sensitive reporters (firefly and NanoLuc luciferases) for use in dual-assay format. Both reporters give state-of-the-art functionality, raising the question “Which luciferase should be the primary reporter and which should be the control?”

This infographic outlines the various NanoDLR dual-reporter assay choices and the situations where you would choose one format over another.
