• • Protein Interface Analysis

  Protein interface analysis is a scientific technique focused on investigating the external structure of protein molecules and their interactions with the surrounding environment. This surface is not only crucial for the protein's biological functionality but also significantly affects its interactions with drugs, ligands, and other proteins. Typically, the protein surface comprises amino acid residues exposed to the solution, and the chemical properties, spatial distribution, and dynamic changes of th......

• • Label-Free Protein Quantification

  Label-free protein quantification (LFQ) is an advanced technique for proteomics data analysis. By obtaining protein mass spectrometry data, researchers can perform relative quantification of proteins across different samples without the use of stable isotope labeling. LFQ determines the relative protein abundance in a sample by comparing the intensity and number of mass spectrometry peaks. Since this method does not require additional chemical reagents for sample processing and relies solely on the hi......

• • Glycosylation Mass Spectrometry

  Glycosylation mass spectrometry is a critical technique for analyzing glycosylation modifications in biomolecules, including proteins and lipids. Glycosylation involves attaching sugar molecules to proteins, lipids, or other molecules. Mass spectrometry fundamentally operates by ionizing molecules in a sample, then separating and detecting them based on their mass-to-charge ratio (m/z). In glycosylation mass spectrometry, biomolecules undergo processing to release sugar chains or produce peptide fragm......
