HUPO Biological Reference Material Initiative Workshop 26 September 2009, Toronto, Canada

The Biological Reference Material Initiative Workshop held at the Toronto HUPO congress on 26 September 2009, focused on the development of new biological reference materials and tools for the assessment of reproducibility, the solutions to many of the technical challenges in proteomics and protein‐based molecular diagnostics. This half‐day meeting included presentations from leading scientists from the worldwide proteomic community, who shared a common interest in standardization and increased accuracy of proteomic data. The conclusion was that proteomics is highly sensitive to both biological and technical variability. It is this biological and technical variance, when not accounted for by experiment design, that invalidates proteomic experiments, but both of these issues can be dealt with by tackling reproducibility.
