Study Title | Global profiling for human feces |
Study Summary | The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that responds to a variety of structurally diverse exogenous and endogenous small molecules. Gut microbiota utilizing tryptophan and indole metabolism as a reservoir, has been demonstrated to provide an abundant source of AHR ligands. So untargeted global profiling was performed to find the potential candidates of AHR activator in human feces. |

Sample Preparation:
Sampleprep ID: | SP001419 |
Sampleprep Summary: | Freeze dried human stool (~ 30 mg) were mixed with 1 mL of ice cold 80% methanol (v/v) containing 0.1% formic acid (v/v). Each mixture was homogenized with 1 mm zirconium beads using a BeadBlasterTM 24 (Benchmark Scientific, Edison, NJ, USA) homogenizer. All samples were homogenized according to the program parameters: 6500 - 1×30 - 005 (×3). After vortexing, samples were sonicated for 20 min in an ice water bath, prior to centrifugation at 20,000 × g for 20 min at 4 ℃. The supernatants were collected, dried in a Savant SpeedVac (Thermo Scientific, Waltham, MA, USA), and reconstituted in 100 μL of 3% methanol (v/v) containing 1 µM chlorpropamide (internal standard). |
