High Throughput Metabolomics using 96-plex Isotope Tagging

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Liquid Chromatography-mass spectrometry (LC-MS) based metabolomics suffers from extended duty cycles and matrix-dependent quantitation. Chemical tags with 96 unique masses are reported which alleviate the metabolomic workflow bottleneck and allow for absolute quantitation. A metabolic screen for carboxylic acids was performed on mammalian cells deprived of various nutrients and showed 24% RSD and analysis of 288 samples in 2 hours.
