Identification of Factors Complicating Bioluminescence Imaging

BioRxiv : the Preprint Server for Biology

In vivo bioluminescence imaging (BLI) has become a standard, non-invasive imaging modality for following gene expression or the fate of proteins and cells in living animals. Currently, bioluminescent reporters used in laboratories are mostly derivatives of two major luciferase families: ATP-dependent insect luciferases and ATP-independent marine luciferases. Inconsistent results have been reported for experiments using different bioluminescent reporters and users are often confused when trying to choose an optimal bioluminescent reporter for a given research purpose. Herein, we re-examined inconsistency in several experimental settings and identified factors, such as ATP dependency, serum stability, and molecular size, which significantly affected BLI results. We expect this study will make the research community aware of these factors and facilitate more accurate interpretation of BLI data by considering the nature of each bioluminescent reporter.
