ProteinLogic closes Private Placing – 24 March 2009

CAMBRIDGE, UK (2009-03-24) -FOR IMMEDIATE RELEASE ProteinLogic closes Private Placing

CAMBRIDGE, UK (17th March 2009) ProteinLogic Ltd (the Company) is pleased to announce that it has raised a total of just over £426,000 from a mix of existing shareholders and a number of new investors.

After taking into account the costs of the placing, ProteinLogic has a net cash balance of circa £400,000 with which to fund the continued development of the business and ProteinLogic’s ImmiPrint diagnostic technology. The directors anticipate that this funding will be sufficient to take the company through to the next major milestones in the development of its pattern recognition disease diagnosis technology.

The placing was co-ordinated by Loeb Aron & Company Ltd and Beer & Partners Ltd with the latter firm introducing a number of investors. One investor in particular has considerable experience of growing companies in the healthcare sector and is actively providing assistance to the company as required. ProteinLogic would like to thank both Loeb Aron and Beer & Partners for both ensuring a successful placing in volatile markets and introducing the Company to investors with a deep knowledge of the sector.

The technology was developed by Dr César Milstein and Dr Adrian Woolfson at the MRC Laboratory of Molecular Biology in Cambridge and Professor Nick Hales from the Department of Clinical Biochemistry at the University of Cambridge. The technology is based partly on Milstein’s discovery of immune cell surface antigens and his work on monoclonal antibodies, for which he was awarded the Nobel Prize in Medicine and Physiology.
