Hematech, Sioux Falls' flagship biotechnology research outfit, on Friday laid off 18 people in response to the changing needs of its parent company. Hematech research focuses on developing antibodies in cattle to treat human health conditions. The company once envisioned becoming a major manufacturer of the human antibodies, although its focus has switched to research. The layoffs included researchers, technicians and support staff, according to Eddie Sullivan, Hematech chief operating officer.
