From Wikipedia, the free encyclopedia
EosFP is a photoactivatable green to red fluorescent protein. Its green fluorescence (516nm) switches to red (581nm) upon UV irradiation of ~390nm (violet/blue light) due to a photo-induced modification resulting from a break in the peptide backbone near the chromophore.[2] Eos was first discovered as a tetrameric protein in the stony coral Lobophyllia hemprichii[3]. Like other fluorescent proteins, Eos allows for applications such as the tracking of fusion proteins, multicolour labelling and tracking of cell movement[4]. Several variants of Eos have been engineered for use in specific study systems including mEos2, mEos4 and CaMPARI.
