Application and Breakthrough of Mass Spectrometry Technology in Amino Acid Sequencing

The research and production of biological drugs are crucial to the development of human health and the medical field. In the field of biopharmaceuticals, understanding the amino acid sequence of proteins is essential for drug design, production, and quality control. With the continuous advancement of science and technology, mass spectrometry has become an important tool for determining amino acid sequences in the field of biological drugs. 

 

Mass spectrometry is a method that can analyze and measure compounds. It is based on the mass and charge ratio of molecules to identify and quantify compounds in samples. In the determination of amino acid sequences, mass spectrometry can infer amino acid sequences by measuring the mass of peptide segments. The advantages of high sensitivity, high resolution, wide mass range, and diverse analysis modes make mass spectrometry the preferred method for amino acid sequence determination in the field of biopharmaceuticals.

 

Application of Mass Spectrometry in New Drug Research and Development

In the process of new drug research and development, understanding the amino acid sequence of proteins is crucial for understanding their function, structure, and interaction. Mass spectrometry can help scientists understand the relationship between the structure and function of proteins by measuring the amino acid sequence of drug candidate molecules. In addition, mass spectrometry can also be used to determine the purity of drugs and identify possible variations and modifications, providing important support and verification for the development of new drugs.

 

Application of Mass Spectrometry in Quality Control of Biological Drugs

In the production process of biological drugs, quality control is a crucial link. Mass spectrometry can be used to verify each stage of the production process to ensure the quality and consistency of biological drugs. By determining the amino acid sequence, mass spectrometry can detect and quantify possible variations, modifications, and impurities, providing key quality control information. In addition, mass spectrometry can also be used to detect possible additional components and contaminants in biological drugs to ensure the safety and purity of drugs.

 

Breakthroughs and Future Prospects of Mass Spectrometry

With the continuous development and innovation of mass spectrometry, the demand for the accuracy, sensitivity, and high-throughput analysis of amino acid sequence determination are constantly increasing. The introduction of new generation mass spectrometry instruments and analysis methods, such as high-resolution mass spectrometry (HRMS) and tandem mass spectrometry (MS/MS), makes the determination of amino acid sequences more accurate and reliable. In addition, the combination of mass spectrometry with other analytical technologies, such as proteomics and metabolomics, can more comprehensively understand the interactions and regulatory mechanisms of proteins and metabolites in biological systems.

 

The application and breakthrough of mass spectrometry in amino acid sequence determination are of great significance to the field of biopharmaceuticals. It not only helps scientists understand the relationship between the structure and function of proteins in new drug research and development but also ensures the quality and consistency of drugs in the quality control of biological drugs.
