This report studies the Keyhole Limpet Hemocyanin (KLH) market, KLH, which can be used as an active pharmaceutical ingredient (“API”), is a very large, high molecular weight, oxygen-carrying glycoprotein made of millions of atoms. There are two KLH subunit forms, KLH1 and KLH2, each composed of seven or eight functional units, with each functional unit having an oxygen binding site of two copper atoms. Keyhole limpet hemocyanin is an extremely large, heterogeneous glycosylated protein consisting of subunits with a molecular weight of 350,000 and 390,000 in aggregates with molecular weights of 4,500,000-13,000,000. Each domain of a KLH subunit contains two copper atoms that together bind a single oxygen molecule (O2). The KLH protein is potently immunogenic yet safe in humans and is therefore highly prized as a vaccine carrier protein.
KLH protein is derived only from the hemolymph of the giant keyhole limpet (megathura crenulata), which is native only to a limited stretch of the Pacific Ocean coastline along Southern California and Baja California, Mexico.
The major players in global Keyhole Limpet Hemocyanin (KLH) market include biosyn Corporation, Stellar Biotechnologies, etc. The top 2 players occupy about 90% shares of the global market. Europe and North America are main markets, they occupy almost the entire market. Research Grade is the main type, with a share over 85%. Laboratory is the key application, which hold a share about 90%.
