Metaproteomics Analysis Service

Protein is the direct embodiment of gene function. Metaproteomics refers to all the proteins expressed by environmental microorganisms at a specific moment. The research types of Metaproteomics are very diverse, such as microorganisms in active sludge, marine microorganisms, soil microorganisms, fermented food microorganisms, intestinal microorganisms, feces, mucosal cavities, etc. On the basis of microbial metagenomic data, further research on its corresponding protein composition and function will be able to deeply explore the abundance distribution and functional orientation of functional molecules in the microbial population.

A large number of studies have demonstrated the application of metaproteomics in studying the functional role of gut microbiota in health and disease. Metaproteomics can not only study the composition and metabolic changes of the gut microbiota in disease states, but also consider the dynamic changes of biochemical pathways related to the disease.

Creative Proteomics has a high-resolution tandem liquid chromatography mass spectrometry platform (LC-MS/MS), based on the label-free proteomics Shotgun technology to elucidate gut microbes. In addition, we can also implement one-stop, personalized data analysis to help realize data visualization.

Which samples are more suitable for metaproteomics?

1. The composition is complex and there are many interferences
2. A wide variety of microorganisms
3. Largely affected by external environmental factors (season, temperature, humidity, etc.)
4. Complicated spatial location
5. The existence of other living things, such as animals and plants

What information can you obtain?

  • Get all the protein information from different species in the sample
  • The composition and function of the microbial community in the sample can be analyzed to reveal the relationship between microorganisms and the environment
  • Reveal the changing classification, function, and metabolic pathways in the sample microbiota

Technology Platform of Metaproteomics Analysis

  • Electrospray tandem mass spectrometry (ESI-MS/MS)
  • Nano liquid chromatography tandem mass spectrometry (LC-MS/MS)
