• • Cellular IP Product Mass Spectrometry Detection

  Immunoprecipitation (IP) combined with mass spectrometry (MS) is a widely used approach for investigating protein-protein interactions and quantifying protein expression levels. The integration of these techniques enables molecular-level analysis of biological processes, providing detailed insights into protein function and cellular mechanisms.

• • Protein Mass Spectrometry Analysis of Antigen Types

  The immune response is the physiological reaction of an organism to foreign antigens, initiated by antigen-antibody interactions. Antigens, typically proteins or polysaccharides, provoke an immune response. Accurate identification and classification of antigens are vital for understanding and manipulating immune responses. Recently, protein mass spectrometry analysis has been employed to identify and classify antigens.

• • Proteomics Can Analyze Specific Functional Proteins

  Proteomics is a scientific discipline dedicated to investigating protein expression, localization, interactions, and functions within cellular systems. It provides critical insights into the complexity and dynamic nature of biological processes. This paper explores the application of proteomics in the analysis of proteins with defined functional roles.

• • Exosome Peptide Detection

  Exosomes are extracellular vesicles secreted by cells throughout their lifecycle. They typically measure between 30 and 150 nanometers in diameter and are enclosed by a phospholipid bilayer, allowing them to exist freely in various body fluids. The cargo of exosomes includes proteins, lipids, RNA, and DNA, rendering them ideal for indicating cellular status and function.

• • Are There Differences in Proteomics Between Serum and Plasma

  In proteomics research, blood samples, including serum and plasma, are widely used biological specimens. Although both are derived from blood, they exhibit key differences in biochemical composition, biological function, and applications in proteomics studies. Definition of Serum and Plasma: Plasma is the liquid component of blood that remains after most red blood cells, white blood cells, and platelets have been removed. It contains a variety of dissolved electrolytes, proteins, hormones, and metabolic....
