  The primary structure of an antibody, that is, its amino acid sequence, contains a wealth of information. Bioinformatics, as an interdisciplinary field, provides us with powerful tools and techniques for interpreting the primary structure of antibody drugs. This article will focus on the application of bioinformatics in the primary structure of antibody drugs, and discuss its importance in sequence analysis, structure prediction, and function prediction.

• • Parallel Reaction Monitoring (PRM) Method in Protein Post-Translational Modificationomics

  Proteomic Post-Translational Modification (PTM) is a branch of science that studies the overall status and dynamic changes of protein post-translational modifications. It involves various types of PTM, such as phosphorylation, acetylation, SUMOylation, ubiquitination, methylation, etc. To efficiently and accurately detect and quantify the PTM status of proteins, mass spectrometry techniques, particularly targeted spectrometry methods like Parallel Reaction Monitoring (PRM), have been widely utilized.

• • Mass Spectrometry Detection of Protein Molecular Mass

  In the field of scientific research, mass spectrometry technology plays a key role in detecting the mass and structure of proteins. Compared to other protein detection methods, this technology can provide more direct and accurate results, which is why it is highly favored by researchers.   Simply put, mass spectrometry detection is the process of providing a substance with enough energy to ionize it, producing atoms or molecules with positive and negative charges.

• • Protein Primary Structure Determination

  Protein structures can be divided into four levels: primary, secondary, tertiary, and quaternary structure. The primary structure of a protein refers to the linear sequence composed of amino acids. Each amino acid is connected by a peptide bond to form a polypeptide chain. The primary structure of a protein determines the formation of its secondary, tertiary, and quaternary structures, which in turn determines the functions and interactions of the protein.

• • Protein Ubiquitination Sites Identification by Mass Spectrometry

  Ubiquitination modification is an important post-transcriptional modification of proteins in living organisms, with profound effects on many physiological processes such as gene expression, cell cycle regulation, and immune responses. However, the accurate identification of ubiquitination sites and their specific biological significance is one of the frontier challenges in the field of biopharmaceuticals.
