| Study Title | Natural abundance of isotopic metabolite detection in mouse eye orgnaoids. |
| Study Summary | Because the natural abundance of isotopic metabolites in the early eye organoids has not yet been reported, we have performed LC-MS/MS without exogenous isotopic labeling to show the natural abundance of isotopic carbons. Cell Name AES0145 : Rx-GFP K/I EB5 (RIKEN Cell Bank): Organoid method (PMID: 21475194). |

| MS Comments: | The capillary of the ESI source was set to 275 °C, with sheath gas at 35 arbitrary units, auxiliary gas at 5 arbitrary units and the spray voltage at 4.0 kV. In positive/negative polarity switching mode, an m/z scan range from 60 to 900 was chosen and MS1 data was collected at a resolution of 70,000. The automatic gain control (AGC) target was set at 1 × 106 and the maximum injection time was 200 ms. The top 5 precursor ions were subsequently fragmented, in a data-dependent manner, using the higher energy collisional dissociation (HCD) cell set to 30% normalized collision energy in MS2 at a resolution power of 17,500. Besides matching m/z, metabolites are identified by matching either retention time with analytical standards and/or MS2 fragmentation pattern. Data acquisition and analysis were carried out by Xcalibur 4.1 software and Tracefinder 4.1 software, respectively (both from Thermo Fisher Scientific) |
