 (fī′kō-bī′lə-prō′tēn′, -tē-ĭn)
Any of a group of water-soluble fluorescent proteins that are covalently attached to phycobilins in cyanobacteria and red algae. They are widely used for research and industrial purposes, especially as fluorescent tags and as dyes.

In our case, possibly IAA separated pigments by hydrophobic interaction with N-H groups of the proteins and by low relatively density of this solvent compared with water (LIDE, 1998) (Figure 2), especially phycoerythrin, a red protein-pigment complex from the light-harvesting phycobiliprotein family, which is easily extracted from Rhodophyceae, in which it play an important protective role against oxidative damage provoked by excess light exposure, and have several biotechnological applications for various fields, including food, medicine and aquaculture (CARDOZO et al.
On the other hand, PC is a phycobiliprotein of large dimensions (121,000 Da in its trimeric form, and approximately 40,000 Da in its monomeric form).

It also contains a unique blue pigment, phycobiliprotein, which is only found in blue-green algae," said Gerald Cysewski, PhD, founder and chief science officer, Hawaii-based Cyanotech.

In contrast to green algae, cyanobacteria contain phycobiliprotein pigments (e.

The presence of the phycobiliprotein phycocyanin was confirmed by the fluorescence method of Stewart & Farmer (1984), thereby placing the isolate unequivocally in the cyanobacteria; this fluorescence spectrum was identical to that of Synechococcus sp.
