• • Specific Protein Quantification

  Specific protein quantification is a technique used to precisely measure the concentration of target proteins in complex biological samples. This process involves multiple methods and technologies, with mass spectrometry (MS) being one of the most widely used techniques. MS is commonly applied in proteomics research, biomarker discovery, and drug mechanism studies. Enzyme-linked immunosorbent assay (ELISA) is another method for specific protein quantification. ELISA utilizes high-affinity antibody binding..

• • SILAC-Based Proteomics

  SILAC-based proteomics is a powerful and precise technique used to study protein expression and modifications in cell biology and molecular biology. SILAC, or Stable Isotope Labeling by Amino Acids in Cell Culture, is a method that enables quantitative protein analysis by incorporating stable isotope-labeled amino acids into cells during culture. The core principle of SILAC-based proteomics is the replacement of natural amino acids with stable isotope-labeled ones (e.g., ¹³C or ¹⁵N-labeled lysine and.......

• • Glycoprotein Enrichment

  Glycoprotein enrichment refers to the selective extraction and concentration of glycosylated proteins from complex biological samples using specialized techniques. Glycoproteins are proteins that contain covalently attached glycan structures and are fundamental components of various biological systems, including cell membranes, secreted proteins, and serum proteins. As a major post-translational modification, glycosylation significantly influences protein function, stability, localization, and interactions.

• • Hydroxyproline Analysis

  Hydroxyproline analysis is a specialized technique for quantifying hydroxyproline in biological samples and investigating its role in various biological processes. Hydroxyproline is a hydroxylated amino acid that plays a pivotal role in collagen biosynthesis. As the most abundant structural protein in the human body, collagen is extensively distributed in tissues such as skin, bone, and blood vessels, where it is essential for maintaining structural integrity and cellular function. Given that hydroxypr.....

• • Lipidome Analysis

  Lipidome analysis technology is a technique specifically designed to study the composition of lipid molecules in organisms, their metabolic pathways, and the roles of lipids in physiological and pathological states. Lipids are the main components of cell membranes and are also key molecules in energy storage and signal transduction. Lipidomics systematically analyzes lipid molecules in cells, tissues, or body fluids to reveal their multiple roles in biological processes. The application of lipidome ........
