Main activity areas
The laboratory staff has a consolidated experience in the development, production, purification and characterization of recombinant proteins, antibodies and antibody-derivatives, as well as in the customized monoclonal antibodies generation through hybridoma technology.
The laboratory activities also include design and validation of immunoassays (ELISA), affinity and binding analyses by SPR, preparation of tech-transfer protocols for biosimilar industrialization, and recombinant enzymes manufacturing.
Main Technologies
The laboratory has at its disposal multiple host strains and cell lines, as well as a large library of IP-free expression vectors for the production of recombinant proteins and antibodies.
The laboratory performance is ensured by the design of project-specific and tailored strategies and by the use of cutting-edge tools and methods. Finally, the possibility of using advanced analytical techniques, such as SPR, HPLC and LC-MS/MS, makes possible a complete characterization of the produced bio-molecules.
