About Protein Sciences Corporation Protein Sciences Corporation, founded in 1983, is a privately held biotechnology company located in Meriden, Connecticut, USA. The Company focuses on the development and commercialization of recombinant vaccines and biopharmaceuticals based on the Company’s patented manufacturing platform BEVS (Baculovirus Expression Vector System). Protein Sciences’ lead product candidates are Flublok against seasonal influenza, and Panblok against pandemic influenza. Protein Sciences is one of only a few companies in the world to develop recombinant vaccines produced in non-mammalian cells using genetically modified baculovirus. Some advantages compared to traditional vaccine manufacturing are that it requires less lead time to manufacture, the products are not produced in eggs and therefore do not contain egg derivatives, and the manufacturing does not require the use of live influenza virus, thimerosal or antibiotics. Protein Sciences also partners with select companies on product development and manufacturing, and sells proteins for research purposes. The Company is for example the contract manufacturer of the active ingredient GAD for Diamyd Medical’s antigen-based diabetes therapy Diamyd®. Diamyd Medical holds about 8 percent of the shares in Protein Sciences Corporation. On August 31, 2012, the carrying amount of this holding was MSEK 28.4.
