Fig. 4From: An ambient-temperature storage and stabilization device performs comparably to flash-frozen collection for stool metabolomics in infantsHierarchical clustering analysis (HCA) of the relative abundance of metabolites in Frozen vs. OMNImet.GUT fecal samples collected at 2 timepoints. The HCA was generated using the merged data including the 1064 metabolites detected in both the Frozen and OMNImet.GUT tubesBack to article page
