Figure 4From: Molecular preservation by extraction and fixation, mPREF: a method for small molecule biomarker analysis and histology on exactly the same tissue Relative levels of metabolites from alcohol extracts of biopsies using the mPREF method categorized by prostatectomy pathology class. Box and whisker plot distributions; box lower quartile to the upper quartile; whiskers, minimum and maximal values without outliers; line, median value. x-axis categories: T2, pathology stage T2, organ-confined disease; T3, pathology stage T3, non-organ-confined disease; neg, biopsy did not contain tumor; pos, tumor present in biopsy. y-axis: relative amount based on mass spectrometry ion counts.Back to article page
