C-phycocyanin Antibody

The light-harvesting antenna system in red algae and cyanobacteria is formed of phycobilisomes composed of phycobiliproteins: phycoerythrin (CPE), phycocyanin (CPC) and allophycocyanin (APC). The phycobiliproteins all share the same subunit composition (heterododecamer of 6 alpha and 6 beta chains) and organization with variations in the covalently bound open-chain tetrapyrrole chromophores.
