1. Supplementary data 2: Reproducibility of metabolite MSI Reproducibility of MSI data was evaluated by mean ± standard deviation (5 biological replications). Error bars indicate standard deviation. All standard deviations were within 20% indicating similarity of individual measurement. As an example, the MSI images of glucose-6-phosphate for 5 biological replications were represented here.
