Phycobiliproteins are water soluble fluorescent proteins derived from cyanobacteria and marine algae. Several different types have been characterized, and two of these (R-phycoerythrin and allophycocyanin) have become workhorse fluorescent detection reagents in a wide range of biotechnology applications.Agilent phycobiliproteins are manufactured from proprietary natural sources grown in continuous culture in California. These highly purified products are then purified yielding the highest quality phycobiliproteins availableFor Research Use Only. Not for use in diagnostic procedures.
