CORRECTION: In an article published in the January 4 issue of BioArray News, “Microarray Challenge 2002: To Transform Hot New Technology into Products and Revenues,” Biocept of San Diego, which produces protein arrays with hydrogel droplets, was referred to erroneously on page 5 as Biosite. Biosite, also a protein chip developer, has released a chip that quantifies proteins from damaged heart tissue. BioArray News regrets this inaccuracy.
