Several dozens of research and technical experts have successively established world-class technical platforms, including prokaryotic cell expression, eukaryotic cell expression, baculovirus expression, monoclonal/polyclonal expression, antibody recombinant expression, and nanobody technology. These platforms have served as the foundation for the development and production of hundreds of varieties of biologically active proteins. These proteins cover a wide range of series including infectious diseases, vector-borne diseases, respiratory diseases, inflammatory conditions, cancer marker, zoonotic diseases, and animal (pets/livestock) disease screening. This extensive range ensures the application of common immunodiagnostic products, all developed and produced using these cutting-edge platforms.
