Sample Preparation and Services
- The QC analysis of enzymatic hydrolysis is strictly controlled by LC-MS
- DDA-Spectral Library generated using HPLC technology and sample fractionation
BGI has extensive experience in the field of metaproteomics spanning microorganisms research across human fecal samples, water samples, and fermentation liquor samples.
Since its inception in 2004, metaproteomics aims at the large-scale characterization of all proteins expressed by environmental microbiota at a given point in time, which can better promote the in-depth study of the diversity, structure and potential gene function of the microbial community1.
DDA analysis can be carried out if there are no suitable library construction samples:
DIA analysis can be carried out if there are suitable library construction samples:

Metaproteomics services are performed using nano-flow liquid chromatography and cutting-edge mass spectrometer (Q Exactive HF/HF-X and Orbitrap Fusion Lumos).
We accept protein samples in a variety of formats. For attaining maximum proteome coverage, we recommend utilizing our sample fractionation services, performed using our off-line HPLC platform.
Please be sure to send the sample after enrichment.
