| Study ID | ST001032 |
| Study Title | Single-cell Profiling of Cationic and Anionic Metabolites in Live Frog (Xenopus) Embryos using Microprobe Capillary Electrophoresis Mass Spectrometry |
| Study Type | Metabolic profiling of single cells |
| Study Summary | The goal of this study was to enable the analysis of anionic and cationic metabolites from the same identified single cell in Xenopus laevis embryos. A 10 nL portion of identified animal-ventral (V1) cells was aspirated from 8-cell embryos, and metabolites were extracted from the aspirate, before characterization of cationic and anionic compounds using a custom-built capillary electrophoresis (CE) electrospray ionization (ESI) mass spectrometry platform. A total of ~250 cationic molecular features and ~150 anionic molecular features were detected, including 76 metabolites that were identified in this study. Pathway analysis of the identified metabolites highlighted arginine-proline metabolism of significance. |
