• • Liquid Chromatography Mass Spectrometry

  Liquid chromatography mass spectrometry (LC-MS) is an analytical technique that combines the capabilities of liquid chromatography and mass spectrometry. Liquid chromatography is employed to separate the components of a mixture, while mass spectrometry is utilized to detect and identify these separated components. The separation process in liquid chromatography relies on the differences in distribution coefficients of various compounds between the stationary phase and the mobile phase. Following sepa......

• • Receptor-Ligand Binding Assay

  Receptor-ligand binding assays are among the core techniques for studying molecular interactions and play a crucial role in life sciences and drug development. The binding of receptors and ligands underpins many biological processes, such as cellular signal transduction, metabolic regulation, and immune responses. Receptors can be proteins located on the cell surface or within the cell, while ligands may include small molecules, peptides, nucleic acids, antibodies, or other proteins. By investigating ......

• • Vaccine Development

  Vaccine Development encompasses the entire process from initial antigen discovery to final clinical trials and regulatory approval. Vaccines are designed to prevent infectious diseases by stimulating the immune system to produce specific antibodies, providing protection against future infections. The core of vaccine development lies in identifying and validating antigens capable of inducing effective immune responses. With advancements in proteomics, genomics, and bioinformatics, these technologies ar......

• • Functional Proteomics

  Functional proteomics is a scientific discipline dedicated to studying protein functions within cells and organisms, focusing on elucidating their biological roles and dynamic changes under specific conditions. By integrating proteomics technologies with functional analyses, this field investigates protein roles in both physiological and pathological processes, providing valuable insights into life sciences. Unlike traditional proteomics, which primarily emphasizes protein identification and quantif......
