PE Biosystems and Purdue University to Collaborate on New Technologies for Food Safety

Melding of leading-edge automated systems and academic research will explore new methods of safeguarding food and water supply.

FOSTER CITY, CA, June 30, 2000 -- PE Biosystems Group (NYSE: PEB), a PE Corporation business, and the Food Science department of Purdue University, West Lafayette, Indiana, are collaborating to develop new methods of detecting and tracking food-borne pathogens. PE Biosystems will provide the university with its proprietary ABI PRISM® genetic analysis systems, reagents, software, and technical support for food microbiology research. These products will also help educate future food technologists in the use of molecular tools. In return, PE Biosystems will have access to information that Purdue scientists have amassed about food-borne pathogens. The goal of the collaboration is to accelerate new tests and systems for ensuring food safety. To further that goal and to better understand the needs of major food producers and manufacturers, PE Biosystems has become a member of Purdue's Industrial Associates Program. PE Biosystems has also granted scholarships to two students in the university's Food Science department.

"Purdue's Food Science department is the largest in the country and has conducted extensive research into food safety," said Elaine Heron, Ph.D., vice president, PE Corporation, and general manager, Applied Biosystems Division. "That expertise, combined with our technology resources, creates an excellent opportunity to develop systems that ensure safer food production and distribution in the United States and throughout the world."

"PE Biosystems leadership in the development of DNA-based detection methods will add significant value to our program," said Philip E. Nelson, Ph.D., professor and head of the Purdue Food Science department. "Through this relationship, students will gain experience with new technologies that can be used to detect food-borne pathogens more rapidly."

As bacteria mutate and new strains emerge, researchers have discovered that they can achieve rapid, accurate detection and identification of organisms only with DNA analysis techniques. The leader in the development of genetic analysis systems, PE Biosystems applied these technologies to produce a series of molecular-based assays for the detection, identification, and characterization of pathogenic E.coli, Salmonella, and other bacteria transmitted through food sources. These assays include TaqMan® Pathogen Detection Kits, MicroSeq™ Bacterial and Fungal Identification Kits, and Microbial AFLP® Strain Typing Kits.

The Purdue University Department of Food Science is recognized worldwide for its expertise in aseptic processing, carbohydrate research, and computer-integrated manufacturing. It combines cutting-edge technology, expanded research experience, and forward-looking, comprehensive classes in applied microbiology and biochemistry to improve the taste, nutrition, and value of the world's food supply. Graduates are qualified for careers in quality assurance, product development, research, sales, technical services, purchasing, and production management.
