Genentech Inc., is a biotechnology corporation which became a subsidiary of Roche in 2009. Genentech Research and Early Development operates as an independent center within Roche.〔(【引用サイトリンク】title=About Us )〕 As of November 2014, Genentech employed nearly 12,900 people. In July 2014, Genentech announced its acquisition of Seragon for up to $1.725 billion. ==History== The company was founded in 1976 by venture capitalist Robert A. Swanson and biochemist Herbert Boyer.〔"Genentech was founded by venture capitalist Robert A. Swanson and biochemist Dr. Herbert W. Boyer. After a meeting in 1976, the two decided to start a biotechnology company, Genentech. Although the two confidently assert that it was the first biotech company, others clearly came before, including Cetus Corporation which was founded in 1971." (【引用サイトリンク】title=Corporate Overview )〕 Boyer is considered to be a pioneer in the field of recombinant DNA technology. In 1973, Boyer and his colleague Stanley Norman Cohen demonstrated that restriction enzymes could be used as "scissors" to cut DNA fragments of interest from one source, to be ligated into a similarly cut plasmid vector. While Cohen returned to the laboratory in academia, Swanson contacted Boyer to found the company.〔〔"In January 1976, 28-year-old venture capitalist Robert Swanson entered the picture. A successful cold-call to Boyer's lab led to a couple of beers—and an agreement to start a pharmaceutical company. Investing $500 each, they capitalized a new business, Genentech, to seek practical uses for Boyer and Cohen's engineered proteins. Swanson raised money for staff and labs..."(【引用サイトリンク】title=Who made America? Herbert Boyer )〕 Boyer worked with Arthur Riggs and Keiichi Itakura from the Beckman Research Institute, and the group became the first to successfully express a human gene in bacteria when they produced the hormone somatostatin in 1977. David Goeddel and Dennis Kleid were then added to the group, and contributed to its success with synthetic human insulin in 1978. The Swiss global health-care company F. Hoffmann-La Roche AG now completely owns Genentech after completing its purchase on March 26, 2009, for approximately $46.8 billion.
