Abstract

The identification and cloning of a red fluorescent protein (DsRed) obtained from Anthozoa corals has provided an alternative to commonly used green fluorescent proteins (GFPs) in bioanalytical and biomedical research. DsRed in tandem with GFPs has enhanced the feasibility of multicolor labeling studies. Properties of DsRed, for example high photostability, red-shifted fluorescence emission, and stability to pH changes have proven valuable in its use as a fluorescent tag in cell-biology applications. DsRed has some limitations, however. Its slow folding and tendency to form tetramers have been a hurdle. Several different mutational studies have been performed on DsRed to overcome these problems. In this paper, applications of DsRed in biosensing, specifically in FRET/BRET assays, whole-cell assays, and in biosensors, is discussed. In the future, construction of DsRed mutants with unique characteristics will further expand its applications in bioanalysis.
