• • Photoaffinity Labeling in Target and Binding Site Identification

  Photoaffinity labeling in target and binding site identification represents an advanced approach at the interface of chemistry and biotechnology. It is designed to accurately elucidate the interactions between small molecules and their protein targets, with a particular focus on the spatial localization and binding mechanisms of interaction sites. In contemporary drug discovery and molecular mechanism studies, understanding where and how small molecules engage with target proteins underpins the .........

• • GTEx Proteomics

  GTEx (Genotype-Tissue Expression) Proteomics represents a systematic research initiative that extends the scope of the original GTEx project. It aims to construct a comprehensive landscape of protein expression across diverse human tissues and to further investigate how genetic variation influences the spatial distribution and functional modulation of proteins. While the initial GTEx project primarily focused on uncovering inter-individual variability and tissue specificity in gene expression using ........

• • Detection Methods for Changes in Protein Glycosylation Levels

  Glycosylation is a crucial post-transcriptional modification process that influences the folding, stability, activity, and intercellular interactions of proteins. There are various methods to determine if the glycosylation modification level on a protein has changed, and each method has its characteristics and applicable scenarios. Here are some commonly used techniques: 1. Mass Spectrometry (MS) MS is a very powerful tool, especially when combined with liquid chromatography (LC-MS/MS)

• • TAILS Proteomics

  TAILS proteomics (Terminal Amine Isotopic Labeling of Substrates) is a high-resolution proteomic strategy designed to characterize the structural features of protein N-termini and to identify protease cleavage sites. This approach involves chemical labeling of protein N-terminal amines using isotopic reagents, followed by selective enrichment and mass spectrometry analysis, enabling sensitive and systematic detection of both native N-termini and neo-N-termini generated by proteolytic processing.

• • Principles of Proteomics

  Proteomics is an important research field in the biopharmaceutical industry, which focuses on the study of the entire collection of proteins in an organism, helping us to gain deeper insights into the physiological and pathological processes of living organisms. Proteins are the most diverse and functionally rich molecules in living systems, and understanding the principles of proteomics is pivotal in exploring the molecular mechanisms within cells and organisms.

• • Detection of Protein Phosphorylation Levels at Specific Sites

  Quantitative analysis of phosphorylation levels plays a crucial role in studying cell signaling, disease development, and drug mechanisms. The phosphorylation level at specific sites reflects the activity status of proteins and their involvement in biological processes.
