Applera

Applera Corporation of Norwalk, Connecticut, at #874 on the 2007 Fortune 1000 list, was one of the largest international biotechnology companies based in the United States. It was the successor company to what was the Life Sciences Division of Perkin-Elmer Corporation. Applera was not publicly traded, but instead it consisted of two major groups which are publicly traded tracking stocks in the proteomics industrial sector. These two groups were the S&P 500 listed Applera Corp-Applied Biosystems Group of Foster City, California, and Applera Corp-Celera Genomics Group of Rockville, Maryland. In 2006, the company spun off the Celera Genomics group and changed its name from Applera to Applied Biosystems.
