Abstract

Critical need to rapidly and quantitatively measure the chemistry of single cells in their natural state, without extensive sample preparation procedures. Developed at ORNL an innovative single cell droplet ejection-liquid vortex capture mass spectrometry (SCDE-LVC-MS) platform for rapid, in situ molecular characterization of single cells in suspension. This platform provides rapid, quantitative, targeted and/or untargeted mass spectrometric analysis of single cells without extensive sample preparation procedures. Enable real-time untargeted mass spectrometry analysis of chemical constituents of single cells in their native environment. Send a TTL signal via a connected AD/DA board to start mass spectrometry (MS) data acquisition - analyze MS data - classification of analyzed samples (e.g. separate single cell types based on their chemistry) - quantitation of analyzed samples (e.g. quantify lipids in single cells). List of features: external instrument control; screen capture; reporting; real-time MS data (single cell) analysis; classification; quantitation. Specific application: real-time mass spectrometry analysis of chemical constituents of single cells in their native environment. The software starts MS acquisition; then monitors a folder where the Cytena Single Cell Printer saves images of ejected single cells; real-time extracts MS spectra from MS files for a) either classification of single cells, or b) quantitation of (a) chemical constituent(s) of single cells.
