South San Francisco-based Genentech Inc. posted a 50% rise in revenue for the year ended Dec.31, 1986. Fourth-quarter revenue also was up, compared to the same period last year. Genentech, a leading biotechnology company focusing on the development, manufacture and marketing of pharmaceuticals produced by recombinant DNA technology, said: “With the purchase of the assets of the (two R&D;) partnerships, Genentech now has exclusive U.S. ownership of the products developed by the partnerships: Protropin human growth hormone, gamma interferon and Activase tissue plasminogen activator.” The acquisition of these products will have a positive impact on Genentech’s future earnings through increased profit margins and tax benefits, a spokesman added.
