• Determination of Protein Disulfide Bonds
The structure and function of proteins largely depend on their three-dimensional structure, and disulfide bonds, as one of the important covalent bonds in proteins, play a crucial role in maintaining the stability and functionality of proteins. Therefore, accurate determination of protein disulfide bonds is of great significance for understanding the structure and function of proteins.

• Protein Phosphorylation Detection: Methods and Applications
Protein phosphorylation is an important post-translational modification process, involving the addition of a phosphate group to a specific amino acid residue of a protein, typically serine, threonine, or tyrosine residue. Protein phosphorylation plays a critical role in regulating various biological processes within cells, including signal transduction, cell cycle, and metabolism.

• Proteomic Identification of Human Cell Proteins
The cell is the basic unit of life, and proteins are the key players in cell function and structure. In order to gain a deep understanding of cell function, growth, division, and their relationship with diseases, comprehensive identification and functional analysis of proteins are crucial. In this regard, mass spectrometry (MS) technology provides powerful tools for proteomics.

• Determination of Primary Structure of Fish Tissue Protein
As one of the main sources of food for humans, fish meat is rich in protein and has high nutritional value. In-depth research on the primary structure of proteins in fish meat not only helps to understand the nutritional composition and biological activity of fish meat, but also has important implications for food science, aquaculture, and pharmaceutical research.

• Vitreous Humor Tissue Protein 2D Electrophoresis Analysis
The vitreous humor tissue is a crucial tissue in the eye and plays a vital role in the normal functioning of the visual system. It contains various proteins that are closely related to eye diseases, aging, and other physiological processes. Therefore, the identification and quantification analysis of its proteins are of great significance.

• Comparison of Proteomics Analysis
Comparative proteomics is a branch of proteomics that involves comparing protein expression in different biological samples, such as cells in healthy and diseased states or cells from different species. This comparison can reveal which proteins have changed under specific conditions, helping scientists understand disease mechanisms, identify biomarkers, and even discover new therapeutic targets.

Drug antibody testing is a laboratory testing method specifically designed to evaluate the immune response of the human body to certain drugs. This test is commonly used to monitor a patient's immune response to biological agents or other drugs, especially in the treatment of chronic diseases such as autoimmune diseases, certain cancers, and inflammatory diseases. The principle of drug antibody testing is based on the recognition and response of the immune system to drug molecules.

TMT is a chemical labeling method used for quantitative proteomics. Peptides from different samples are chemically labeled with different isotopic labels. These labels are designed to have the same mass, but when broken down in a mass spectrometer they will release different reporter ions. The relative abundance of peptides in different samples can be determined by comparing the intensities of these reporter ions.
-
Targeted proteomics is a mass spectrometry method that focuses on studying a specific set of proteins or peptides, in contrast to traditional global proteomics analysis. Targeted proteomics typically uses selected reaction monitoring (SRM) or multiple reaction monitoring (MRM) techniques to specifically detect and quantify specific peptide segments.

• Protein Amino Acid Composition Analysis
Protein amino acid composition analysis is to understand the basic composition of proteins by determining the types of amino acids they contain and their relative molar ratios. This analysis method is commonly used to identify, quantify and study the chemical properties and structure of proteins and peptides. Below are some techniques commonly used for protein amino acid composition analysis:
