Membrane Protein Antibody Discovery Service
Membrane Protein Antibody Discovery Service is designed to identify high-affinity, highly specific, and functionally active monoclonal antibodies against complex membrane protein targets such as GPCRs, ion channels, transporters, and viral envelope proteins. This is achieved through the reconstruction of native-like antigens and the application of multi-platform antibody screening technologies, providing essential molecular tools for functional membrane protein studies and therapeutic development.
Membrane proteins serve as key executors for transmembrane signaling and material exchange between the cell and its environment. They play vital roles in cell recognition, transmembrane transport, immune response, and disease pathogenesis. GPCRs, ion channels, transmembrane enzymes, and viral envelope proteins have emerged as highly attractive antibody drug targets in the field of biopharmaceuticals.
Membrane protein antibodies are antibody molecules that specifically recognize and bind to membrane proteins, targeting distinct epitopes in their native conformations or functional states. These antibodies form a critical link between basic membrane protein research and the advancement of precision medicine.
