Collection:
Collection ID: | CO001446 |
Collection Summary: | Extracellular metabolite dynamics was analyzed during primed to naïve conversion in the bioreactor. For this, the media of H1 hESCs in the bioreactor was gradually switched from mTESR1 to RSeT media within 6 days of culture (D2 to D6) and the media was collected every day for the analysis. For H9 hESCs, the extracellular metabolites were analyzed in the spent media of primed and established naïve (P5) hPSCs in the bioreactor, and the media of each primed or naïve hPSCs was collected at day four of bioreactor culture. |

Sample Preparation:
Sampleprep ID: | SP001459 |
Sampleprep Summary: | The metabolite extraction was started using LC-MS or HPLC grade methanol (Sigma-Aldrich, 1.06035). Briefly, a 950 μL of pre-chilled 50% MeOH/H2O was added to a 50 μL of the bioreactor-collected media (making a D20 dilution), and the samples were incubated on ice for 30 min to allow for full extraction. Macromolecules were then pelleted by centrifugation at max speed (~18,000-21,000 g) for 10 mins in a bench top centrifuge (preferably chilled) to extract the supernatant. Further, the extracted samples were stored in -80 prior to running HPLC-MS. |
