Non-targeted metabolomics can detect all metabolites in biological samples without bias, and screen the differential metabolites in the control group and the experimental group. Pathway analysis can further explain the biological role of differential metabolites in the metabolic pathways involved.

Based on NMR, GC-MS and LC-MS platforms, Creative Proteomics integrates HMDB, LipidSearch, MoNA, MassBank, METLIN, self-built database system and independent core algorithm to provide you with global and accurate non-targeted metabolomics analysis. We aim to accelerate the progress of the project by providing high quality data and comprehensive analytical reports for biopharmaceutical and research institutions.
