Phycobiliproteins are water-soluble fluorescent proteins derived from cyanobacteria and Eukaryotic algae. In these organisms they are used as accessory or antenna pigments for photosynthetic light collection. They absorb energy in portions of the visible spectrum that are poorly utilized by chlorophyll and through fluorescence energy transfer, convey the energy to chlorophyll at the photosynthetic reaction centre. Phycobiliproteins are easily conjugated to streptavidin and antibodies using traditional methods. Browse our Product Catalogue to find a wide selection of Phycobiliproteins and Phycobiliprotein conjugates. Far East Bio-Tec Co. manufacturers the algae by fermentation in two locations in California. In this way cells can be harvested and Phycobiliproteins purified before any deterioration of the molecule occurs. They are very pure. By always harvesting the cells at the same time, the cells are remarkably consistent lot to lot; hence the Phycobiliproteins are remarkably consistent lot to lot.
