MetabolomicsA combined direct infusion/reversed phase chromatography – high resolution mass spectrometry workflow for accurate absolute lipid quantification with 13C- internal standards
We propose a fully automated novel workflow for lipidomics based on flow injection, followed by liquid chromatography-high-resolution mass spectrometry (FI/LC-HRMS). The workflow combined in-depth characterization of the lipidome achieved via reversed-phase LC-HRMS with absolute quantification by us...

MetabolomicsAbsolute quantification of metabolites in tomato fruit extracts by fast 2D NMR (Tomato 700 MHz samples)

Quantitative NMR metabolomics is a powerful tool to have access to valuable information on metabolism. Unfortunately, the quantitative analysis of metabolic samples is often hampered by peak overlap. Two-dimensional (2D) spectroscopy offers a promising alternative and quantitative results can be ...

MetabolomicsAbsolute quantification of serum cytokines and metabolome reveals the glycylproline regulating antibody-fading in convalescent COVID-19 patients

The COVID-19 pandemic has incurred tremendous costs worldwide and is still threatening public health in the 'new normal'. The association between neutralizing antibody levels and metabolic alterations in convalescent patients with COVID-19 is still poorly understood. In the present work, we condu...

TranscriptomicsAbsolute quantification of protein production reveals principles underlying protein synthesis rates
A quantitative view of cellular functions requires precise measures of the rates of biomolecule production, especially proteins-the direct effectors of biological processes. Here we present a genome-wide approach, based on ribosome profiling, for measuring absolute protein synthesis rates. The resul...

TranscriptomicsGlobal absolute quantification reveals tight regulation of protein expression in single Xenopus eggs
Recent developments in genomic sequencing technology have enabled comprehensive transcriptome analyses of single cells. In contrast, single cell proteomics analyses have been restricted to targeted analyses, for example using flow cytometry with GFP fusions or mass cytometry. Here, we performed glob...

TranscriptomicsAbsolute quantification of miRNAs
MicroRNAs (miRNAs) have been shown to play an important role in many different cellular, developmental, and physiological processes. Accordingly, numerous methods have been established to identify and quantify miRNAs. The shortness of miRNA sequence results in a high dynamic range of melting tempera...
