St. Louis-based biotech giant Sigma-Aldrich Corp., which has more than 6,000 employees and operations in 34 countries, confirmed that it will continue with a major expansion of a local biotech facility it acquired last year.
The company said the project will add 38,000 square feet to the 23,500-square-foot building at 645 Science Drive in University Research Park that houses what was Tetrionics. The former Tetrionics is now part of SAFC, a custom chemical manufacturer and a division of Sigma-Aldrich.
