Competing Interests

The authors have read the journal's policy and have the following conflicts. All authors except KJJ are employed by Novo Nordisk A/S and hold shares in Novo Nordisk A/S. There are no products in development or marketed products to declare. A patent application covering B25C insulin analogue has been filed and will become publicly available in September 2012. The methods and results described in this article are not the subject of this application. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials, as detailed online in the PLoS ONE guide for authors (http://www.plosone.org/static/policies.action#sharing).
