Collection:
| Collection ID: | CO001903 |
| Collection Summary: | Animals were sacrificed, blood and cecum tissue were removed, snap frozen in liquid nitrogen and stored at -80°C until further analysis |
| Sample Type: | Cecum |
Treatment:
| Treatment ID: | TR001923 |
| Treatment Summary: | RYGB surgery was performed on age-matched (8-10-weeks old) male Wistar IGS rats. After four weeks of recovery, animals were put on an antibiotic cocktail consisting of ampicillin (1 g/l; Ratiopharm), vancomycin (0.5 g/l; Ratiopharm), neomycin (1 g/l; Bela-pharm), and metronidazole (1 g/l; CP-Pharma), provided freshly every day via drinking water. The parallel FMT group received fecal RYGB microbiota transplantation once per week, but were otherwise handled like DIO littermates. For fecal transplantation experiments, 100 mg of fresh stool from bodyweight-stabilized RYGB donors was re-suspended in 1 ml of PBS, homogenized carefully and administered via oral gavage with 200 μl of the suspension. |
Sample Preparation:

| Sampleprep Summary: | Sample preparation for MetIDQ p180 Kit measurement Solvents: Acetonitril (Merck KGaA, Darmstadt, Germany hypergrade for LC-MS) Water MiliQ, Extracting agent - ACN / H2O (1:1) Equipment 4 steel balls size M Eppendorf Tubes 2mL Tissue slicer (Rettberg, Germany) Centrifuge (Sigma) Work steps Approximately 100mg of caecum sample and 4 steel balls of size M into each tube. Per mg of sample 5µL of extracting agent was added. Shake the samples for 10 minutes at 30 Hz in the tissue slicer and centrifuge for 2 minutes at 14000 rpm. 10 µL supernatant was used for the targeted analytics. Blood serum samples 10 µL were used for analysis Kit reparation The analysis was performed using the validated MetIDQ p180 Kit and described in Siskos et al. [1]. Data processing was carried out with the provided quantitation method Kit (Biocrates Life Sciences AG, Innsbruck, Austria). 1 Siskos AP, Jain P, Römisch-Margl W, Bennett M, Achaintre D, Asad Y, et al.
