“This agreement represents the latest step in our strategy to build the most comprehensive offering in biochemical and cellular screening for drug discovery,” said Robert F. Friel, president and chief executive officer, PerkinElmer, Inc. “Our customers will benefit from direct access to Cerep’s expertise in high throughput screening and profiling services, while PerkinElmer will be able to extend the reach of our leading assay technologies and assay development services into key drug discovery markets.”
