Quality GMP Natural Pigment Phycocyanin,China price supplier

Phycocyanin is a pigment-protein complex from the light-harvesting phycobiloprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiloproteins are water-soluble, so they cannot exist within the membrance like carotenoids can. Instend, phycobiliproteins aggregate to form clusters that adhere to the membrance called phycobilosomes. Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly near 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 wavelenghts than phycocyanin C or phycocyanin R. Phycobiliproteins have fluorescent properties that are used in immunoassay kits. Phycocyanin is from the Greek phyco meaning "algae" and cyanin is from the English word "cyan", which conventionally means a shade of blue-green (close to "aqua") and is derived from the Greek "kyanos" which means a somewhat different color:"dark blue". The product phycocyanin, produced by Aphanisomenon flos-aquae and Spirulina, is for example used in the food and beverage industry as the natural coloring agent "Lina Blue" and is found in sweets and ice cream.

C-phycocyanin is often found in cyanobacteria which thrive around hot springs, as it can be stable up to around 70ºC, with identical spectroscopic behaviours at 20 and 70ºC. Thermophiles contain slightly different amino acid sequences making it stable under these higher conditions. Molecular weight is around 30,000 Da. Stability of this protein invitro at these temperatures has been shown to be substantialy lower. Photo-spectral analysis of the protein after 1 min exposure to 65ºC conditions in a purified state demonstrated a 50% loss of tertiary structure.
