Product Name

NebuChem™ C-Phycocyanin

Catalog Number

NBC-242144

Description

NebuChem™ C-Phycocyanin (CAT#NBC-242144) is a blue-green, water-soluble pigment present in photosynthetic bacteria and cyanobacteria. Composed of alpha and beta subunits connected by a covalent bond, it functions as a biliprotein.

NebuChem™ C-Phycocyanin (CAT#NBC-242144) has a purity of more than 3.0. 

Background

Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane called phycobilisomes. 

Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly 620 nm (depending on which specific type it is), and emits fluorescence at about 650 nm (also depending on which type it is). Allophycocyanin absorbs and emits at longer wavelengths than phycocyanin C or phycocyanin R. Phycocyanins are found in cyanobacteria (also called blue-green algae). Phycobiliproteins have fluorescent properties that are used in immunoassay kits.
