Northfield Closes Blood Replacer Plant

Department: Business

Northfield Laboratories is closing its plant in Mount Prospect, Ill., and laying off its entire staff there, effectively ending its effort to develop a red blood cell substitute. Late last month, the company received a letter from FDA stating that the agency would not approve the product, a chemically modified hemoglobin called PolyHeme. Northfield is one of several firms trying to develop blood substitutes (C&EN, Feb. 23, page 52).
