Monoclonal antibodies are produced by immortal hybridoma cells created from the fusion of antibody-producing splenic B-cells and myeloma cells, or by recombinant protein expression in mammalian cells. These antibodies have monovalent affinity and bind to a single epitope on the antigen. Purification is commonly accomplished through Protein A/G/L affinity chromatography.

GeneTex offers a broad selection of monoclonal antibodies directed against the majority of key targets/proteins in the spectrum of biomedical research.
