Competing Interests

All authors are employees of Roche. Rituximab is a marketed Roche product. The aim of the study was to get additional insights into the mode of action of anti-CD20 antibodies, which is obviously also in the interest of the authors' employer. The authors confirm that this does not alter their adherence to all the PLoS ONE policies on sharing data and materials.
