Label
R-Phycoerythrin (PE) is an oligomeric protein complex (270 kDa) from red algae that exhibits intensely bright red-orange fluorescence with high quantum yields. The complex consists of six heterodimers, α subunit (18 kDa) and β-subunit (20 kDa), and an additional γ-subunit (34 kDa).  PE is covalently attached randomly through lysines on the target protein.
