Study TitleSingle-cell Profiling of Cationic and Anionic Metabolites in Live Frog (Xenopus) Embryos using Microprobe Capillary Electrophoresis Mass Spectrometry
Study TypeMetabolic profiling of single cells
Study SummaryThe 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.
