Phycobiliproteins

Phycobiliproteins are natural polymers of proteins found in cyanobacterai, eukaryotic red algae, and cryptophytes where they are accessory pigments of photosynthesis. Within the seaweed, they are grouped into packages of phycobiliproteins organized around architectures called phycobilisomes, the collector complexes of light energy.

We produce four types of phycobiliproteins : APC & APC XL, C-PC, R-PE, B-PE. In order to perfectly meet the needs of our custumers, we offer these phycobiliproteins in a precipitated form and a lyophilized form. The latter has many advantages, such as its ability to be directly soluble in buffer while preserving the spectral properties of the pigments.

• Specific absorption coefficient and high-quantum efficiency
• Significant Stokes offsets
• 100% water soluble
• Stable in a large pH range (5 à 8)
• Coupling with organic compounds such as antibodies and other proteins by conventional chemical procedures, without altering their spectral properties
• Excitation by conventional lasers such as helium-neon, krypton, or argon
