In its quest to be taken seriously in the field of proteomics, PerkinElmer has acquired Packard Biosciences, partnered with Genomic Solutions (now being acquired by Harvard Biosciences), and begun developing a MALDI-TOF mass spectrometer with the help of MDS Sciex. Now the former EG&G, which won the rights to PerkinElmer’s name when it acquired the old PerkinElmer’s analytical instrument business in 1999, is turning to veteran proteomics researcher Mary Lopez.
