R-Phycoerythrin (Cat No.:M052290) is a bright red, water-soluble phycobiliprotein found in red algae, composed of alpha, beta, and gamma subunits with covalently attached bilin chromophores. It exhibits intense fluorescence with high quantum yield, making it an excellent fluorescent marker in flow cytometry, fluorescence microscopy, and immunoassays. R-PE absorbs light maximally around 488–565 nm and emits strongly at approximately 575–585 nm. Its strong photostability, high molar extinction coefficient, and ability to conjugate with antibodies make it ideal for sensitive detection in biological and diagnostic applications. It is stored and handled under light-protected conditions.
