Cupp-Sutton, Kenneth Smith. Analyte molecules extracted both from solutions and cell samples were analyzed using nanoelectrospray ionization (nanoESI) directly from the nanopipette into a mass spectrometer. Recent advances in single-cell ultra-trace analysis. Quantitative live cell mass spectrometry analysis at a subcellular level requires the precisely controlled extraction of subpicoliter volumes of material from the cell, sensitive analysis of the extracted analytes, and their accurate quantification without prior separation. This observation indicates that the approach developed in this study enables quantitative analysis of small volumes of metabolites extracted from cells.
