Nimbus Changes Name to Sovicell GmbH

Leipzig, Germany; 11th March 2008 – Nimbus Biotechnologie, the trusted supplier of ADME-Tox products and services, has announced that it has changed its name to Sovicell GmbH, effective immediately. At the same time the Company has launched a new website at www.sovicell.com. The name change reflects the Company’s move to become a full range, international supplier of ADME-Tox products and services for pre-clinical research. It is also a reflection of the growth in the business in the last year under a new more internationally focused management team.

Commenting on the name change Dr Hinnerk Boriss, CEO said: “This name change supports our Company’s commercial development and more accurately reflects our new positioning. We are continually enhancing our ADME-Tox product portfolio and services to meet our pharmaceutical and biotechnology customers’ needs and look forward to continuing to work with our supportive existing partners as well as expanding our client base internationally.”

Since its foundation in 1994, Sovicell (formerly Nimbus) has successfully developed and commercialised its proprietary TRANSIL® bead-based in vitro testing procedures for reliably measuring a drug candidate’s membrane permeability and protein binding. Such testing can enable early and accurate prediction of the efficacy and safety of drug candidates and prevent costly failures in clinical trials. Last year the Company began enhancing the portfolio and now provides cryopreserved hepatocytes exclusively for Cytonet.

In addition, since 2007 Sovicell (formerly Nimbus) has been offering a blood-to-brain adsorption kit which is based on natural biological membranes and is valuable in the development of CNS drugs. This is the only product of its kind available on the market. Further new products are to follow shortly.

To further facilitate the continued expansion of Sovicell’s business, the Company recently moved to new state-of-the–art premises in Leipzig’s BioCity: Deutscher Platz 5b, 04103 Leipzig Germany.
