Competing Interests

Alicia Newton, Christos J. Petropoulos, and Wei Huang are employees of Monogram Biosciences. From roughly 2008 - August 2010 Celia Schiffer served as a consultant to Monogram Biosciences, on topics unrelated to this research and thus has no competing interest. Since the completion of this research project Celia Schiffer has received small "Sponsored Research Grants" from Avila (CelGene) and Merck. This does not alter our adherence to all PLoS Pathogens policies on sharing data and materials.
