• • 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.

• • Analyze the Dynamic Changes of Histone Modifications Using Mass Spectrometry

  Histone modification is an important regulatory mechanism in cells, affecting gene expression by altering the structure and function of chromatin. Recent developments in mass spectrometry technology have allowed us to further investigate the dynamic changes in histone modification.

• • Protein Translation and Post-Translational Modification Detection Methods

  Post-translational modifications (PTMs) are key biochemical processes in cells that modify the chemical properties, structure, function, and location of proteins. Common post-modification of proteins includes phosphorylation, acetylation, ubiquitination, glycosylation, pantothenylation, etc. Detecting these modifications is crucial for understanding the role and regulatory mechanisms of proteins. Below are the commonly used methods to detect protein post-translational modifications:

• • Profiling Cell Surface Proteins by Orbitrap Mass Spectrometry
