Company description:

Cetek Corporation, founded in 1996, collaborates with pharmaceutical and biotech companies to screen for therapeutic candidates in natural products, combinatorial mixtures, and synthetic libraries. The company's proprietary CE Assay technology offers unmatched ability to identify samples with strong hits, and rank them according to relative binding strength. Compared to conventional assay methods, it provides significant competitive advantages: Most importantly, the technique is able to detect valuable hits that other assays miss, while eliminating non-specific interferences, weak binding hits and false positives. The method consumes dramatically less sample and reagents and allows very rapid assay development.

Cetek is a privately-held corporation located in Marlborough, Massachusetts. The CE Assay technology was originally developed at the Barnett Institute of Northeastern University by Cetek co-founders Dallas E. Hughes, PhD. and Barry L. Karger, PhD.
