Verouden, M.P.H. (author), Westerhuis, J.A. (author), van der Werf, M.J. (author), Smilde, A.K. (author), TNO Kwaliteit van Leven (author)In metabolomics research a large number of metabolites are measured that reflect the cellular state under the experimental conditions studied. In many occasions the experiments are performed according to an experimental design to make sure that sufficient variation is induced in the metabolite concentrations. However, as metabolomics is a...article 2009
