Collection:
| Collection ID: | CO001954 |
| Collection Summary: | Urine was collected from individual mice in metabolic cages after overnight (12 hours) fasting with ad libitum access to water. Since Ndufs4 KO mice yielded limited urine volumes, urine droplets that failed to reach the collection tube were also collected. Hence, the separating cone, collection funnel and urine collection tubes were all treated with sodium azide (NaN3; 0.1% w/v; WT: 100 μL and KO: 50 μL) to prevent bacterial growth. Samples were snap-frozen in liquid nitrogen upon collection and stored at −80 °C until used. |
| Sample Type: | Urine |
| Storage Conditions: | -80℃ |
Treatment:
| Treatment ID: | TR001973 |
| Treatment Summary: | The animals did not receive any treatment |
Sample Preparation:
| Sampleprep ID: | SP001967 |
| Sampleprep Summary: | Pre-determined volumes of urine, containing 0.0625 μmole creatinine, were supplemented with internal standards and deproteinized using methanol. Urine samples were then dried under nitrogen and derivatized (methoxymated and silylated) prior to analysis. |

| MS Comments: | The LECO Corporation ChromaTOF® software (v 4.5x) was used for data acquisition and extraction. This included automatic baseline removal via the “spanning” tracking method (offset of 1; just above the noise) and auto smoothing, with the software’s Statistical Compare feature used to align peaks. Spectral matching was done using the NIST11 commercial library and an in-house mass spectral library in order to identify important analytes. |
