The Seaport Innovation District alone encompasses more than 4 million square feet of life science space, anchored by Eli Lilly’s 346,000-square-foot Seaport Innovation Center — a state-of-the-art R&D hub dedicated to RNA and DNA-based therapies. In the Longwood Medical Area, world-renowned research hospitals — Massachusetts General, Brigham and Women’s, Dana-Farber Cancer Institute, Boston Children’s — operate sophisticated research cleanrooms where the stakes are patient outcomes and regulatory standing. Vertex Pharmaceuticals’ 1.1 million sq. ft. Seaport headquarters — the largest biotech footprint in Boston by square footage — anchors the district’s commercial-scale presence, while Ironwood Pharmaceuticals’ downtown Boston headquarters at 100 Summer Street develops and commercializes GI and rare disease therapies distributed nationwide.

Boston cleanrooms span an extraordinary range: early-stage cell culture laboratories, GMP-compliant biologics suites, hospital research facilities, and full-scale commercial manufacturing. Every type demands a different approach — and CleanTech has served all of them. As the Editor of ISO 14644-5, the international standard governing cleanroom operations, we don’t just follow the rules. We wrote them.
