Red fluorescent proteins (RFP) can be imaged on existing confocal or widefield microscopes, and they also have more penetrating power. The excitation and emission maxima of RFP are 558nm and 583 nm, respectively.
The use of RFP, however, has been hampered with several issues. RFP is an obligate tetramer - thus, it forms large aggregates inside cells. This makes the use to RFP to report the location of a protein severely limited.
Although GFP can successfully fuse with several hundreds of proteins, RFP-conjugated proteins are often toxic. Some variants of RFP have overcome these limitations. For example, DsRed2 fluorescent protein does not form aggregates and has reduced toxicity, while another variant of RFP (known as RedStar) has increased brightness and maturation rate.
