C-Phycocyanin
R-PE (R-Phycoerythrin)
Storage : 4℃
Ex (nm) / Em (nm) : 565 / 575
Solvent : Water
Molecular Formula :
Molecular Weight : ~240,000
CAS Number/Name :
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. |
