Figure 3. Authentication of metabolites identified in urine and liver of Hmgn5^tm1/Y and Hmgn5^+/y littermate wild mice.

MSMS fragmentation patterns (A–E) were compared against authentic standards. All spectra were acquired in positive mode (ESI+) with the exception of phenylacetylglycine (C), which was acquired in negative mode (ESI−). Retention time and mass of the parent compound are indicated for each sample and standard comparison.
