Figure Lengend Snippet: (A) Untargeted full-resolution 1H NMR profile of E. coli and spectral expansion between 6.8 and 7.2 ppm. NMR spectra in gray or orange correspond to IBAT or individual batches, respectively. (B) Radial plot representing the coefficient of variation (CV) for annotated metabolites using the same colors. The length of spokes corresponds to the CV of each metabolite. (C) Each data point represents the mean-centered peak height in each sample. Experimental IBAT samples are depicted in orange, and individual batches are depicted in gray. Cyan data points represent the simulated metabolite peak heights per number of averaged batches. Light gray-shaded areas represent ±1 standard deviation from the mean.
