Chloroplast Metabolomics Analysis Services

Chloroplast Metabolomics Analysis Services

The main goal of metabolomics is to perform a comprehensive qualitative and quantitative analysis of the temporally and spatially resolved distribution of all metabolites present in a given biological system. Chloroplast is an important organelle for photosynthesis of green plants, and it is the site of countless different chemical reactions.

Creative Proteomics provides a one-stop service for chloroplast metabolomics analysis, which aims to conduct a comprehensive analysis of chloroplast from a holistic perspective. The main contents include: 1) Aqueous isolation of organelles, non-aqueous isolation of chloroplasts and non-aqueous fractionation of tissues. It can closely approximate the changes of metabolites in chloroplasts; 2) Analysis of multiple metabolic pathways and photosynthesis-related metabolites in chloroplasts; 3) Analysis of metabolic pathways associated with chloroplasts and cytoplasmic matrix and mitochondria; 4) Comparative analysis and evolutionary studies of metabolic networks.

We Provide the Following Services, including but not Limited to:

Our services include targeted and untargeted metabolomics analysis. You can choose according to your experimental purpose and sample.

1. Untargeted Metabolomics Services

Unbiased detection of all small molecule metabolites in the chloroplast. For the analysis of the structure of unknown analytes, we use the hierarchical annotation system based on MS metabolomics research. LC (UPLC)-MS technology is used to collect mass spectra of chloroplast metabolites. Compare the content of metabolites in different groups of samples to find differential metabolites. And explore metabolic pathways between differential metabolites.

2. Targeted Metabolomics Services

Quantify and analyze several target compounds in chloroplast or all or part of metabolites involved in a certain pathway. We have the GC-QToF MS system and developed a large-scale metabolomics quantitative method with the help of MRM (multiple reaction monitoring) or PRM (parallel reaction monitoring) technology. Several compound classes ranging from highly polar compounds of the Calvin cycle to semi-polar plant hormones and non-polar compounds like plant lipids can be detected.

Limitation: Reliable reference compounds are needed to identify and quantify the metabolic profile.
