Bioluminescence as a tool in molecular biology

Journal Title: Advances in Hygiene and Experimental Medicine - Year 2017, Vol 71, Issue

Abstract

Bioluminescence has been studied for many years by scientists. There are numerous mechanisms of that phenomenon; among them bacterial bioluminescence is the most frequently found in nature. This type of bioluminescence is determined by the appearance of lux operon, which encodes all elements necessary to produce light emission and it does not require any additional substrates supply. Another commonly found example of bioluminescence mechanism is performed by Photinus pyralis. Luciferase of P. pyralis named FLuc requires D-luciferin as a substrate. Bioluminescence is also characteristic for many deep-sea organisms. Most of them are based on oxidation reaction of coelenterazine to coelenteramide mediated by RLuc or GLuc luciferases. Due to the variety of bioluminescence mechanisms in nature, it has become possible to apply them in many sensitive methods that can be used in molecular biology and medicine. The most significant application of bioluminescence is BLI (bioluminescence imaging). This method is cheap and nontoxic which allows both in vitro and in vivo imaging. BLI applications include, e.g. protein-protein interactions, stem cells labeling, tracking of viral, bacterial, fungal and parasitical infections, and carcinogenesis analyses. Bioluminescence has also been used in the creation of modified cell systems capable of light emission in response to certain analytes and thus very sensitive biosensors have been generated. Other important areas of bioluminescence application are immunoassays, ATP assays, and BART analysis (bioluminescent assay in Real-Time) – a very sensitive technique which allows scientists to estimate nucleic acids amplification.
