MetabolomicsA Comprehensive and Ultrasensitive Isotope Calibration Method for Soil Amino Compounds Using Orbitrap Mass Spectrometry
Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (~40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and microbial nutrition. The analysis of their content and isotope enrichment still represents a significant...

ProteomicsProteome-wide multipoint internal calibration curves for mass spectrometry-based quantitative proteomics
Mass spectrometry (MS)-based proteomics is known for its high accuracy in quantifying peptides and proteins using various calibration strategies, including internal and external calibration curves. While external multi-point calibration curves are created from serial dilutions, they often fail to ac...

MetabolomicsAbsolute quantification of metabolites in tomato fruit extracts by fast 2D NMR (Calibration Standard 500 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 ...

ProteomicsIsotopologue multi-point calibration for proteomics biomarker quantification in clinical practice
Targeted proteomics has become the method of choice for biomarker validation in human biopsies due to its capacity to measure a set of peptides in multiple samples with high sensitivity, reproducibility, accuracy and precision. However, for targeted proteomics technologies to be transferred to clini...

Metabolomicsmetabolomics Analysis in Cecal Samples
Targeted LC/MS Metabolomics. Cecal contents were lyophilized overnight and approximately 2.5-5 mg was homogenized in 250 µL of 50% acidified acetonitrile (0.3% formic acid) for targeted LC/MS/MS metabolomics (acylcarnitines, amino acids, organic acids, nucleotides, and CoAs) according to validated, ...

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...
