Large Scale Biology is shutting down its fee-for-service proteomics contract business and is “reviewing and evaluating its business, prospects, and programs” in regards to the rest of its Germantown, Md.-based proteomics business, the company said in a series of reports over the past week. The news was punctuated by a sharp 44 percent drop in the company’s stock price on Friday. (The stock has since recovered, but has not reached its Nov. 13 levels.)
