1. Many applications and instruments were developed specifically for R-phycoerythrin . 2. Fluorogenic reporters like phycoerythrin are used in a number of modern immunoassays. 3. R-phycoerythrin is also produced by certain red algae. 4. Phycoerythrin is an accessory pigment to the main chlorophyll pigments responsible for photosynthesis.5. R-phycoerythrin is predominantly produced by red algae. 6. When bound to phycoerythrin , phycourobilin shows an absorption maximum around 495 nm. 7. There are phycocyanin and phycoerythrin subunits that radiate out from this center like thin tubes. 8. Red algae are red due to phycoerythrin . 9. This chromophore is always a donor chromophore of phycoerythrins , since their acceptor chromophore is always phycoerythrobilin. 10. In green light, the cells accumulate more phycoerythrin , whereas in red light they produce more phycocyanin.
