Proteomics is gradually being used to complex bacterial communities. Originally, it was described as the study of all proteins expressed by a single organism. As a result, the study of microbial communities' protein composition, such as the gut microbiota, is now referred to as "metaproteomics." Gut microbiota metaproteomic services are provided by Creative Biolabs to help detect broad protein profiles in complex samples, like the gut microbiota.

Gut Microbiota Metaproteomic Applications
supplying details on microbiomes, such as their composition, dynamics of abundance, the physiology and metabolism of particular organisms, and the host.
providing the localization of putative host-microbe interaction proteins, the absorption of substrates tagged with heavy carbon or nitrogen, and gene expression responses under changing circumstances.

identifying the molecular mechanisms underlying homeostasis and the etiology of disease, as well as the functional functions played by gut microbiota in both health and disease settings.

The discovery of biomarkers to monitor disease activity and prognosis, as well as to distinguish between healthy persons and ill ones (such as those with colon cancer or inflammatory bowel disease).
