• • Versatility of Liquid Phase Analysis Techniques in Proteomics

  In proteomics, liquid phase analysis techniques play a crucial role due to their wide range of applications and ability to provide rich information, which has greatly facilitated the rapid development of proteomics. High-performance liquid chromatography (HPLC) is the most common and fundamental method in liquid phase analysis. In proteomics, HPLC is mainly used for protein separation and purification.

• • What is SG in N-Glycosylation Modification in Mass Spectrometry?

  In the field of biopharmaceuticals, protein modification is no longer just a simple "decoration," but has become an important switch controlling life processes. Among them, N-glycosylation modification has become a widely studied focus.

• • Differences and Connections Between Acetylation and Other Modifications

  Histone acetylation modification is a common post-translational modification of proteins in organisms. It refers to the transfer of acetyl groups from acetyltransferases (HATs) to lysine residues of histones through the transfer of energy. The differences and connections between acetylation and other modification methods reveal the secrets of life.

• • Can Mass Spectrometry Reveal the 3D Structure of Proteins?

  Mass spectrometry is a technique that obtains structural information of compounds by measuring the ratio of molecular ion mass to quantity. In theory, this method should only be sensitive to the mass and charge of substances, not to their shapes and structures.

• • Investigation of Exosome Proteomics Detection Method

  Protein is the most fundamental molecular machinery in organisms, playing important roles in regulating cell functions, transmitting signals, and participating in biological processes. Accurate identification of protein structure and function is crucial for drug development and treatment strategies in the field of biopharmaceutical research. However, due to the complexity and diversity of proteins, their identification has always been one of the challenges faced by biologists.

• • Mechanism of KEGG Pathway Enrichment Analysis

  Pathway enrichment analysis is widely utilized in biological research to understand the functional roles of genes or proteins in various biological processes. KEGG (Kyoto Encyclopedia of Genes and Genomes) is one of the most commonly used bioinformatics resources for pathway enrichment analysis. KEGG pathway enrichment analysis reveals the enrichment of specific biological pathways in a gene set by comparing gene expression differences under different experimental conditions.

• • Application of KEGG Pathway Analysis in Differential Protein Expression

  In proteomics, differential protein expression analysis has become a vital tool for understanding how biological systems respond and adapt to various environmental changes. KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis, a widely used bioinformatics method, helps researchers gain insights into complex protein and gene interaction networks by providing comprehensive functional annotations and pathway information.

• • Workflow of KEGG Pathway Annotation and Enrichment Analysis

  The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis is a widely-used tool in modern biological research, particularly in fields such as genomics, transcriptomics, and metabolomics. The KEGG database aggregates extensive information on genes, compounds, reactions, and their interactions, facilitating the biological annotation of omics data and providing insight into gene function relationships within networks.

• • Advantages and Limitations of KEGG Pathway Analysis

  The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis is one of the widely used tools in bioinformatics and genomics research. It provides a systematic approach for exploring the relationships between genes and proteins within biological pathways and for investigating their roles in various biological processes. Through KEGG pathway analysis, researchers can identify and interpret the functional roles of genes or proteins within complex biological networks.

• • Principle of KEGG Pathway Annotation and Enrichment Analysis

  In bioinformatics and systems biology, the Kyoto Encyclopedia of Genes and Genomes (KEGG) database is a major resource for the systematic study of biomolecular functions. The KEGG database contains extensive information on metabolic and signaling pathways, making it an essential tool for understanding molecular networks and gene functions.
