Introduction to Qualitative Proteome Analysis

Protein is the material basis of life, and the first step in the study of protein is the qualitative analysis of protein. Mass spectrometry technology is used to separate, purify, and enrich cells, tissues or body fluids. All or specific proteins in the protein gel/liquid type sample is then identified before the type of protein in a specific environment is fully understood to provide the basis for proteomics research.

With the development of sequencing technology, the research on protein characteristics is often carried out on a large-scale. As a result, the amount of data obtained has also increased significantly. Therefore, it is necessary to use bioinformatics to fully mine the relevant information. In addition to the use of protein analysis software to predict various parameters, the isoelectric point, molecular weight, primary structure, and secondary structure are verified and analyzed by instruments and equipment. After analyzing the protein in an all-round way combined with the instrument and analysis software, the function and mechanism of the protein are further inferred. We can provide intuitive protein identification results for research on the occurrence and development of diseases and the growth and development of animals and plants. The protein identification and analysis products can be divided into the following two products according to the research object and content: protein full spectrum analysis and glue dot/strip identification.

Bioinformatic Analysis Content

CD Genomics searches the corresponding protein database based on the original data obtained by mass spectrometry, and then performs protein identification based on the results of the database search. At the same time, we can analyze the mass tolerance distribution of peptides, proteins and precursor ions to evaluate the quality of mass spectrometry data, then annotate the identified proteins in conventional functional databases, including COG, GO and KEGG databases. The following analysis content is suitable for full spectrum analysis and strip identification analysis.

Standard analysis content Data output statistics
Protein database search
Preliminary protein identification
Quality control, data filtering
Protein identification results
Protein GO analysis
Protein COG analysis
Protein pathway analysis
Advanced analysis content Relative abundance quantification of single sample protein
