MtoZ Biolabs provides Metaproteomics Services to characterize the functional protein landscape of complex microbial communities across clinical, environmental, and industrial settings. Our metaproteomics services use advanced 4D label-free quantitative proteomics to profile community structure, function, and dynamics at the protein level.
What Is Metaproteomics?
Metaproteomics is the large scale analysis of all proteins expressed by a mixed microbial community within a given environment, such as gut contents, soil, water, biofilms, or bioreactors. Instead of focusing on single isolates, metaproteomics captures the collective proteome of bacteria, archaea, fungi, viruses, and host associated proteins present in a sample.
By identifying and quantifying proteins in situ, metaproteomics reveals which metabolic pathways are active, how microbes interact with each other and with the host, and how community function responds to stimuli such as diet, drugs, pollutants, or environmental change. It links microbial composition to real biochemical activity, providing insight into energy metabolism, nutrient cycling, signaling, virulence, stress responses, and resistance mechanisms. This makes metaproteomics a powerful tool for microbiome research, environmental monitoring, agricultural improvement, industrial fermentation optimization, and translational studies in human and animal health.
Metaproteomics Service at MtoZ Biolabs
MtoZ Biolabs provides end to end Metaproteomics Service built on a 4D-LFQ platform that combines high resolution LC MS, ion mobility separation, and label free quantification. This 4D workflow improves separation of co eluting peptides in complex community samples, increases proteome depth, and enhances quantitative robustness for low abundance proteins.
You only need to define your study objectives and send us your samples. MtoZ Biolabs handles microbial protein extraction from challenging matrices, enzymatic digestion, peptide cleanup, MS acquisition, database search with microbiome focused resources, and downstream bioinformatics. We deliver taxonomic and functional annotations, differential protein and pathway profiles, and clear reports that link microbial community activity to your biological or environmental questions.

FAQ
Q1: What types of samples are suitable?
We accept a wide range of microbiome and environmental samples, including but not limited to:
- Fecal and intestinal content samples
- Soil, sediment, and sludge
- Water and wastewater microbiomes
- Biofilms and bioreactor communities
- Skin, oral, and other host associated microbiome samples
- Cultured microbial consortia and isolated community protein extracts
If you are unsure whether your sample type is suitable, you can contact us for a quick feasibility check.
Q2: How should I prepare my samples?
To ensure high quality metaproteomic data, we recommend:
1. Use fresh or snap frozen samples; avoid repeated freeze–thaw cycles
2. Collect samples in clean, low protein binding tubes or containers
3. For most matrices, provide at least 0.5–1 g (solid) or 0.5–2 mL (liquid) when possible
4. Store samples at −80°C and ship on dry ice
Detailed requirements and recommendations can be found in the Sample Submission Guidelines for Proteomics.
Q3: What is the service general workflow?
Q4: What data formats are provided?
1. Raw data files in instrument specific formats
