Untargeted metabolomics is an analytical approach used for the simultaneous, unbiased analysis of a vast array of compounds that an organism accumulates at a certain point in a given sample, which is used to investigate metabolic phenotypes involving a massive amount of metabolites and elucidate plant-pathogen interactions. Untargeted analyses are especially useful in some cases previous knowledge about the metabolome of the plants or compounds relevant to herbivores is not available. Plant specimens are complex matrices consisting of a myriad of metabolites. Thus, a significant challenge of metabolomics is to identify measured metabolites. Currently, liquid chromatography coupled to mass spectrometry (LC-MS) is the most promising technique for metabolomics in terms of its sensitivity, resolution, precision, throughput, and metabolome coverage. UPLC coupled to high-resolution mass spectrometry (UPLC-MS/MS) is the most commonly used method for untargeted plant metabolomics, which generates a massive amount of data generated. With an integrated set of separation, identification and quantification systems featured with excellent robustness and reproducibility, Creative Proteomics provides reliable, efficient and cost-effective plant untargeted metabolomics services.

Creative Proteomics employs state-of-the-art UPLC-MS/MS systems for plant untargeted metabolomics studies. A non-targeted metabolomic analysis generally consists of these steps: sample collection and homogenization, metabolites extraction, raw data acquisition, data processing, and bioinformatics analysis. We have strong expertise in handling a variety of sample types, and ensure the best recovery and unbiased metabolome measurement.
Our primary instruments include:
- Liquid chromatography system
- Orbitrap MS
- Triple Quad-MS
- Peak calling and metabolite annotation
- Principal component analysis (PCA) and the partial least squares discriminant analysis (PLS-DA)
- Metabolite enrichment and pathway analyses
- Modeling algorithms
- Integrate metabolomics data with lipidomics, transcriptomics, proteomics and phenomics data available
