CD Genomics uses bioinformatics to provide quantitative proteomics and help you explore the data information obtained by different protein quantification techniques. Our unique data analysis skills and the high-quality data analysis platform will exceed your expectations on your personalized data analysis.

Introduction of Quantitative Proteomics

Quantitative proteomics is the accurate identification and quantification of all proteins expressed in a genome or in a complex mixed system. It can be used to screen and find the differentially expressed proteins among samples caused by any factors, and to reveal the physiological and pathological functions of cells combined with bioinformatics. At the same time, some key proteins can be qualitatively and quantitatively analyzed.

Quantitative proteomics refers to the accurate quantitative analysis of the proteins of interest in a single genome sample or a complex mixed system based on protein full spectrum analysis. It can be used to compare the protein content in multiple samples, look for differentially expressed proteins and evaluate their functional characteristics. The input raw data can be obtained by iTRAQ (Isobaric Tags for Relative and Absolute Quantitation) technology, TMT (Tandem Mass Tag) technology, Label-free (protein free-labeled quantification) technology, DIA (Data -independent acquisition) technology, Blood 580 technology and other protein quantification technologies. Relying on powerful information analysis and data processing capabilities, we provide users with efficient protein identification and quantitative analysis services.
