I’ve got a set of experiments planned that, if all goes well, will provide me with the answer I have been seeking for months. Plus, my supervisor is eagerly awaiting the results because she needs the data for a grant application, so I don’t want to mess it up. However, I am faced with a choice for my firefly and Renilla luciferase reporter assays: Do I use the Dual-Luciferase® Reporter Assay System or Dual-Glo® Luciferase Assay System? What’s the difference? How do I decide which to use? I’m so confused! Help!
Sound familiar? Not to worry! The choice is not difficult once you know how these assays work and how they differ.

Reporter gene assays have been critical for the study of a wide-range of biological questions, from regulation of gene expression to cellular signaling. While reporter gene assays constitute a large group of technologies, here we highlight the diversity of new discoveries enabled by highly quantitative and easily measured bioluminescent luciferase-based reporter assays. Below are our top picks of exciting research discoveries involving the Dual-Luciferase Reporter Assay format using firefly and Renilla luciferases.

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. Continue reading “Choosing Primary and Control Reporters for Dual-Luciferase Assays”
The ability to analyze more than one cellular biomarker in a single sample is advantageous for a number of reasons. Multiplexing allows researchers to save money and time, while conserving precious samples. In addition, understanding the relationship between cell biomarkers can provide a more complete picture of cell health that can lead to improved predictive models for drug discovery. Understanding biomarker relationships can also minimize ambiguity in the data set and validate if a treatment effect is real or an artifact of the system. To avoid repeat experiments and extract the most biologically relevant data from multiplex assays, consider these tips when performing multiplex cell-based assays.
