Service Description

We have developed innovative solutions for optimizing the process of comprehensive qualitative and quantitative analysis of all endogenous peptides in complex biological matrices and other complex mixtures.

Peptidomics is an emerging field filling the research gap between proteomics and metabolomics and can be defined as the comprehensive qualitative and quantitative analysis of all endogenous peptides from biological samples at a specific time and location. BGI Genomics has extensive experience in the field of peptidomics spanning disease biomarker study, off target effects of drugs, food processing and fermentation research, the molecular mechanisms of animals and plants, and cell antigen epitopes Prediction^1,2.
