Study ID | ST000330 |
Study Title | Effects of Zinc on GI tract metabolites (Part 1: Esophagus) |
Study Summary | This experiment tested the affects of different diets on mice esophagus metabolites. The diets ranged from zinc sufficient to zinc deficient and a third group that included zinc deficient mice that were put back on zinc sufficient diets. |

Sample Preparation:
Sampleprep ID: | SP000358 |
Sampleprep Summary: | 1. Weigh 50 mg tissue sample in to a 25 ml conical polypropylene centrifuge tube. 2. Add 2.5mL extraction solvent to the tissue sample and homogenize for 45 seconds ensuring that sample resembles a powder. In between samples, clean the homogenizer in solutions of methanol, acetone, water, and the extraction solvent. 3. Centrifuge the samples at 2500 rpm. for 5 minutes. Aliquot 2 X 500µl supernatant, one for analysis and one for a backup sample. Store backup aliquot in the -20°C freezer. 4. Evaporate one 500µl aliquot of the sample in the Labconco Centrivap cold trap concentrator to complete dryness 5. The dried aliquot is then re-suspended with 500l 50% acetonitrile (degassed as given) 6. Centrifuge for 2 min at 14000 rcf using the centrifuge Eppendorf 5415. 7. Remove supernatant to a new Eppendorff tube. 8. Evaporate the supernatant to dryness in the the Labconco Centrivap cold trap concentrator. 9. Submit to derivatization. |
