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

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

A screen of Trp37 mutants of Escherichia coli lipoic acid ligase (LplA) revealed enzymes capable of ligating an aryl-aldehyde or aryl-hydrazine substrate to LplA's 13-residue acceptor peptide. Once site-specifically attached to recombinant proteins fused to this peptide, aryl-aldehydes could be

We present a formalism to quantify the contribution of path-interference in phonon-mediated electronic energy transfer. The transfer rate between two molecules is computed by considering the quantum mechanical amplitudes associated with pathways connecting the initial and final sites. This includes
