Quantitative Proteome Analysis

Relying on advanced sequencing systems and cutting-edge technologies, Creative Proteomics provides global customers with quantitative proteome analysis services. We provide one-stop service for protein extraction, mass spectrometry detection and data analysis, to help you conduct refined proteome studies.


Quantitative Proteome Analysis

Dynamic changes in intracellular proteome abundance have important implications for life processes. For example, the occurrence and development of many diseases are often accompanied by abnormal expression of certain proteins. Quantitative proteomics is the precise identification and quantification of all proteins expressed in a genome or all proteins in a complex mixed system.

At present, quantitative proteomics technology is mainly divided into 2 quantitative strategies: label and label-free. The label strategies are further divided into in vivo labeling (SILAC) and in vitro labeling (iTRAQ, TMT).

It can also be divided into data independent acquisition (DIA) and data dependent acquisition (DDA) according to the data acquisition mode.

Applications of quantitative proteome analysis

  • Changes in protein expression in samples under different treatments and different physiological / pathological states
  • Protein regulatory network research
  • Disease marker screening
