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.

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.

Analysis Note

The product is suspended in 150 mM sodium phosphate, 60% ammonium sulfate, 1 mM EDTA, 1 mM sodium azide, pH 7.0 and must be dialyzed against conjugation buffer or PBS before conjugation.A566/A280 >4.6, A620/A566 <0.03, A566/A498 <1.5

Electric field gradient focusing (EFGF) is a technique used to simultaneously separate and concentrate biomacromolecules, such as proteins, based on the opposing forces of an electric field gradient and a hydrodynamic flow. Recently, we reported EFGF devices fabricated completely from

We describe an optical detection technique that delivers high signal-to-noise discrimination to enable a multi-parameter flow cytometer that combines high performance, robustness, compactness and low cost. The enabling technique is termed "spatially modulated detection" and generates a time-dependent signal as

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

Flow cytometry is the reference technique for assessing ZAP70 expression, a marker of poor prognosis in CLL. One of the most common methods is to assess ZAP70 levels in CLL cells by calculating the ratio between ZAP70 mean fluorescence intensities
