A new high water mark for lab space has been set in the Greater Boston market, and it’s outside of the life science industry’s epicenter in Kendall Square.

Alexandria Real Estate Equities, National Development and Charles River Realty Investors sold their remaining share of Longwood Center to Clarion Partners, part of the existing ownership team, for $349.5 million, or $1,659 per rentable square foot. Alexandria’s 27.5 percent ownership stake was worth $70 million.

The previous record for lab space in Greater Boston was Alexandria’s $725 million purchase of One Kendall in Cambridge in July 2016 for $1,500 per square foot, according to Aaron Jodka, director of research for Colliers International in Boston.

Dana-Farber Cancer Institute is the anchor tenant of the 350,892-square-foot complex at 360 Longwood Ave., occupying 155,000 square feet after having signed a 15-year lease for its Belfer Institute for Applied Cancer Science, as well as other research programs.

Dana-Farber paid $239 million last year to acquire the office condominium for four of its five floors in the 11-story building and a 49 percent interest in the 315-space parking garage. That left the remaining partners with 211,000 square feet occupied by Boston Children’s Hospital, Brigham & Women’s Hospital and four restaurants.

Newton-based National Development will continue to manage the property.
