Fig. 7From: An ambient-temperature storage and stabilization device performs comparably to flash-frozen collection for stool metabolomics in infantsChanges in microbiome modified metabolites (a: aromatic amino acids, b: primary and secondary bile acids) between time points in both Frozen and OMNImet.GUT tubes samples. Heat map representation of statiscally significant metabolites between Time Point 1 and Time Point 2 in frozen and OMNImet.GUT tube samples. Significant (p ≤ 0.05) increases are indicated by red, while significant reductions are represented by greenBack to article page
