R-Phycoerythrin (R-PE) is isolated from red algae.?Its primary absorption peak is at 565 nm with secondary peaks at 496 and 545 nm.?The relative prominence of the secondary peaks varies significantly among R-PEs from different species.?R-PE has three types of subunits: ? (~20,000 daltons), ? (~20,000 daltons) and ? (~30,000 daltons). The molecular weight of intact R-PE has been found to be about 240,000 daltons, and a subunit structure of (??)6 ? has been determined. The ? subunit of R-PE contains only the phycoerythrobilin (PEB) chromophore, while ? and ? subunits contain both PEB and phycourobilin (PUB). Variability in the absorption spectra of R-PEs from various species reflects differences in the PEB/PUB ratio of the subunits. R-PE and closely related B-PE are the most intensely fluorescent phycobiliproteins, with quantum efficiencies probably in excess of 90%, and its orange fluorescence is readily visible by eye in any moderately concentrated solution. Our RPE-iFluor?647 Tandem is an excellent replacement to RPE-Cy5?and RPE-Alexa Fluor?647 Tandem since they have almost identical spectra.
