| Study ID | ST000091 |
| Study Title | Quantitative Metabolomics by 1H-NMR and LC-MS/MS Confirms Altered Metabolic Pathways in Diabetes |
| Study Type | Pre- and Post- insulin study with matched controls |
| Study Summary | We obtained plasma samples from 7 c-peptide negative type 1 diabetic individuals (T1D) and 7 non-diabetic controls (Con) that were matched for age (T1D = 31.1±2.9 yrs, Con = 30.2±3.4 yrs), body mass (T1D = 80.2±4.7kg, Con = 81.9±7.4 kg) and BMI (T1D = 26.5±1.2 kg/m2, Con = 25.2±1.3 kg/m2). Type 1 diabetic people were studied while treated with insulin and also after 8 hours of insulin deprivation |

| Chromatography Summary: | High resolution separation was done using an Acquity UPLC system, injecting 1 l of derviatized solution, with a UPLC BEH C18 1.7 micron 2.1150 mm column from Waters. Column flow was set to 400 l/min with a gradient from 99.9%A to 98%B where buffer A is 1% acetonitrile in 0.1% formic acid and buffer B is 100% acetonitrile. A column temp of 43 degrees Celsius and a sample tray temp of 6 degree Celsius. |
