Description générale

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.

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.

R-Phycoerythrin (R-PE) is a protein acting as a photosynthetic accessory pigment in red algae (Rodophyta). This protein has gained importance in many biotechnological applications in food science, immunodiagnostic, therapy, cosmetics, protein and cell labelling, and analytical processes. In this paper

Mercury, as one of the most prevalent toxic metals released by various natural and anthropogenic processes, causes severe pollution of soil and groundwater. In this work, R-phycoerythrin (R-PE) proteins encapsulated into ZIF-8 composite thin films were prepared via a solid-confinement

Phycoerythrins have been widely used in food, cosmetics, immunodiagnostics and analytical reagents. An efficient one-step chromatography method for purification of R-phycoerythrins from Polysiphonia urceolata was described in this paper. Pure R-phycoerythrin was obtained with an absorbance ratio A(565)/A(280) of 5.6

Phycobilisomes, the light-harvesting antennas in cyanobacteria and red algae, consist of an allophycocyanin core that is attached to the membrane via a core-membrane linker, and rods comprised of phycocyanin and often also phycoerythrin or phycoerythrocyanin. Phycobiliproteins show excellent energy transfer

Even though superresolution microscopy indicates that size of plasma membrane rafts is <20 nm, those structures have never been observed. Förster resonance energy transfer (FRET) is therefore still the most powerful optical method for characterization of such domains. In this letter
