This Excel template is the general (master) template for any type of metabolomics data. It can be used as it is, or extended and modified to create a more specific templates for particular technologies and assay types.

In order to construct an in vivo-like buffer for S. pyogenes, the intracellular concentrations of Fe, K, Mg, Mn Na, P and S elements were determined via ICP-AES (inductively coupled plasma atomic emissionspectroscopy) method at the Institute of Land Use, University of Rostock. The samples for the analysis were obtained from a steady state culture grown on CDM-LAB with glucose.

Follow-up to the validation experiments on FMv2, testing candidate mechanisms for high malate and fumarate accumulation in the Arabidopsis double mutant prr7prr9 and its parent accession Col.

In this study, 14CO2 labelling was used to test the rate of carbon assimilation in the dark at the end of the subjective night (starting about ZT21), which is indicative of PEPC activity in forming malate, and the subsequent partitioning of this labelled C into various cellular fractions. The short-period ...
