Synthetic antibodies are laboratory made proteins designed to mimic the natural antibodies produced by the immune system. Unlike traditional antibodies that are generated inside the body, synthetic antibodies are created using advanced techniques such as computer modeling and laboratory synthesis. This allows scientists to design antibodies with specific shapes and properties to better recognize and bind to particular targets, such as proteins or cells associated with diseases. Synthetic antibodies offer advantages like improved stability, easier production, and the ability to customize their function for research, diagnostic tests, or therapeutic applications. They are increasingly important tools in medicine and biotechnology because they can be precisely engineered to meet specific needs without relying on animals or human donors.
