Phycoerythrin is a phycobilin, one of the three major classes of pigments to be found in plants and algae. R-phycoerythrin is a high added-value protein found in red macroalgae with several interesting properties. After phycobiliproteins are conjugated to secondary antibodies, there is little fluorescence quenching, which results in conjugates of high specific fluorescence compared with conventional fluorophore-antibody conjugates.
