Merck will sell its Diosynth biotechnology manufacturing plant in Morrisville to Fujifilm Holdings of Japan, the companies announced Sunday night.

Diosynth is known as a contract manufacturing organization, and its local facility, which has changed corporate owners several times in recent years, makes products for pharmaceutical and biotech companies in the United States, Europe and Japan.

Fujifilm  is expected to keep Diosynth's 370 local employees in the deal, said Merck spokeswoman Cheznee Johnson.
