Hamilton Thorne Ltd. has acquired the Oosight product line from Cambridge Research & Instrumentation Inc. (CRi) of Hopkinton, a subsidiary of PerkinElmer Inc. Financial terms of the transaction were not disclosed. Oosight provides high-contrast, live images of unfertilized eggs (oocytes), capturing quantitative data of important structures using a patented, noninvasive, polarized-light technique developed by the Marine Biological Laboratory and commercialized by CRi as LC-PolScope technology. Hamilton Thorne is a longtime Oosight distributor. CEO David Wolf said the Oosight system complements his company’s laser products for fertility and developmental biology research laboratories.
