DIA Quantitative Proteomics: Exploring Advantages of Diverse Techniques

Proteomics is a discipline that studies the types, quantities, structures, functions, and interactions of proteins in organisms. In the field of biopharmaceuticals, proteomic technology is widely used for the research and development of biopharmaceuticals, quality control, and pre-and post-clinical evaluations. Among them, protein quantification is an important part of proteomic research. The emergence of dia quantitative proteomics technology has brought new breakthroughs to protein quantification.

 

Dia quantitative proteomics is a quantification method based on data impartiality. Its basic principle is to add a known concentration of internal standard protein in different samples simultaneously, and calculate the concentration of the protein to be measured through the quantification of the internal standard protein. Compared with other quantification methods, dia quantitative proteomics has high throughput, high accuracy, high sensitivity, and high repeatability.

 

Diverse Techniques of Dia Quantitative Proteomics

The development of dia quantitative proteomics technology cannot be separated from diverse technical means. The following are commonly used techniques in dia quantitative proteomics:

 

1. SWATH-MS

SWATH-MS is a quantification method based on data impartiality. It combines data-dependent acquisition and data-independent quantification methods. SWATH-MS technology divides the entire mass spectrum into multiple discrete windows, each window contains multiple ion pairs, and then uses data-dependent acquisition methods to select a certain number of ion pairs for quantification. SWATH-MS technology has high throughput, high accuracy, high sensitivity, and high repeatability.

 

2. DIA-MS

DIA-MS is a quantification method based on data impartiality. It is similar to SWATH-MS, but DIA-MS technology uses continuous windows instead of discrete windows. DIA-MS technology has high throughput, high accuracy, high sensitivity, and high repeatability.

 

3. TMT

TMT is a quantification method based on isotopic labeling. It adds different isotopic labeling reagents in different samples, and then mixes the samples for mass spectrometry analysis. TMT technology has high throughput, high accuracy, high sensitivity, and high repeatability.
