Since 2007 Nycomed maintains the status of a preferred client. In return, Trenzyme maintains the status of a preferred service provider for Nycomed. As such, Trenzyme will continue handling projects ranging from DNA cloning, recombinant expression in E.coli, yeast and mammalian cells to protein purification and cell line development. The geographical proximity of the two companies allows also great flexibility in responding to the scientific demands of projects and is thus considered an important factor for the success of this cooperation. The current agreement running through 2013.
