  • Johnson, Helen E.; Smith, Aileen R.; Mur, Luis A. J.; Causton, David R.; Lloyd, Amanda J. (2007-06-16)
    Metabolomic technologies produce complex multivariate datasets and researchers are faced with the daunting task of extracting information from these data. Principal component analysis (PCA) has been widely applied in the ...

(2010-08)
    Metabolite fingerprinting of Arabidopsis (Arabidopsis thaliana) mutants with known or predicted metabolic lesions was performed by 1H-nuclear magnetic resonance, Fourier transform infrared, and flow injection electrospray-mass ...

  • Johnson, Helen E.; Broadhurst, David I.; Kell, Douglas B.; Theodorou, Michael K.; Merry, Roger J.; Griffith, Gareth W. (2004-03-10)
    Silage quality is typically assessed by the measurement of several individual parameters, including pH, lactic acid, acetic acid, bacterial numbers, and protein content. The objective of this study was to use a holistic ...

  • Dunn, Warwick B.; Johnson, Helen E.; Bailey, N. J. C. (2005-03-04)
    The post-genomics era has brought with it ever increasing demands to observe and characterise variation within biological systems. This variation has been studied at the genomic (gene function), proteomic (protein regulation) ...
  • Smith, Aileen R.; Goodacre, Royston; Johnson, Helen E.; Broadhurst, David I. (2003-03-01)
    The aim of this study was to adopt the approach of metabolic fingerprinting through the use of Fourier transform infrared (FT-IR) spectroscopy and chemometrics to study the effect of salinity on tomato fruit. Two varieties ...
