Xcellerex Inc. has expanded its Marlborough corporate headquarters by 20,885 square feet.
The company now occupies 60,885 square feet at 150-170 Lock Dr., and the 120,000-square-foot building is now completely occupied, according to Richards Barry Joyce & Partners LLC of Boston, the property’s broker.
The building is owned by Davis Marcus Partners.
The building is a mix of office, manufacturing and research and development space.
RBJ brokers said Xcellerex, a biotechnology manufacturing company, had satisfied its need for additional space, and avoided “the sacrifice of operational efficiencies that often accompany a corporate move.”
