| Application: | R-Phycoerythrin (R-PE) is useful in the laboratory as a fluorescence-based indicator for the presence of cyanobacteria and a variety of immunofluorescence applications. R-PE is a useful fluoroprobe in various electrophoretic procedures. R-Phycoerythrin (R-PE) proteins detect mercury ions in soil and groundwater samples. Phycoerythrin has been widely used in food, cosmetics, immunodiagnostics, and analytical reagents. |
| General description: | R-Phycoerythrin or R-PE is a fluorescent probe belonging to the group of phycobiliproteins obtained from macroalgae. R-Phycoerythrin (R-PE) is a protein acting as a photosynthetic accessory pigment in red algae (Rhodophyta). It is an oligomeric protein of 240 kDa, with 6 α (about 20 kDa), 6 β (about 20 kDa), and 1 γ (about 30 kDa) subunits. Phycobiliproteins are water-soluble light-harvesting proteins with a high fluorescent property. |
