Using ALLIGATORs to Capture Circadian Bioluminescence

Abstract

AbstractLuciferases are a popular tool in circadian biology research as longitudinal reporters of gene expression. Here, we describe a short updated protocol for the use of an Automated Longitudinal Luciferase Imaging Gas and Temperature-Optimized Recorder (ALLIGATOR) to record cellular bioluminescence over many days. The ALLIGATOR has superior capacity and flexibility compared with traditional luminometers that employ photomultiplier tubes (PMTs), with high-throughput capability and spatial resolution. It can be readily adapted to a wide variety of applications, such as different sample types and plate sizes, under a wide range of physiologically relevant conditions.
