Antibodies are specialized proteins produced by the immune system that recognize and bind to specific antigens. In research and diagnostics, they are used as precise tools to detect, quantify, and study proteins, pathogens, or other biomolecules. High-quality antibodies enable accurate immunoassays, such as ELISA, Western blotting, and flow cytometry, supporting advancements in molecular biology, immunology, and clinical diagnostics by providing reliable and reproducible results.
