Collection:

Collection ID:CO002293
Collection Summary:For Metabolome, iNs were flow cytometry-isolated 21 days of conversion. iNs were sorted based on the expression of the PSA-NCAM surface markers using PSA-NCAM-PE (Miltenyi) and re-plated on Geltrex-coated wells. The following day, iNs were treated with 2.5 mM DGlucose-C13 for 6 hours and harvested using Tryple. Supernatant and cell pellets were shock frozen in liquid nitrogen.
Sample Type:Biopsy

Treatment:

Treatment ID:TR002312
Treatment Summary:After two weeks of conversion, cells were treated for 10 days with shikonin (10 µM, ChemCruz) before FACS sorting. Control iNs were FACS-sorted and plated on Geltrex-coated wells before transduction with pLVXTP-EGFP-PKM2 or pLVXTP-EGFP. Around 60 % of all neurons were successfully transduced. Five days after transduction, iNs were harvested for MS-analysis. Alternatively, cells were treated with CoDo for 6 hours before harvest.

Sample Preparation:

Sampleprep ID:SP002306
Sampleprep Summary:Metabolites from frozen cell pellets were extracted at 150,000 cells/mL in cold 5:3:2 MeOH:acetonitrile:water. Samples were vortexed 30 min at 4 degrees C then supernatants clarified by centrifugation (10 min, 10,000 g, 4 degrees C). Supernatants were split into two equal tubes and gently dried using a vacuum concentrator. One set of residues were resuspended in 12 uL of 0.1% formic acid (for positive ion mode). The other set of residues were resuspended in 12 uL of 1 mM ammonium acetate (for negative ion mode).
