Laboratory activity

The Center for Proteomics, established in 2006 at the University of Rijeka Faculty of Medicine, is focused on high-throughput monoclonal antibodies (mAb) development for cutting-edge applications, including proteome analysis. It already disposes of a bank with several hundred hybridoma cell lines secreting mAbs to a large variety of target proteins. The Center has participated in more than thirty collaborative projects with prestigious research institutes, universities and biotech SMEs from SE Europe, EU and the USA.

These projects are mainly based on the production and characterization of mAbs for research purposes. In many instances the reagents generated at the Center have played a key role in various discoveries and resulted in joint publications in the leading journals.

Research activities

The Center's pilot project for the high-throughput production of mAbs was performed on the VZV (Varicella Zoster Virus) proteome. Ever since, the Center has been continuously working on new projects and services, which include:

  • generation of diverse sets of mAbs against murine and human cytomegalovirus (CMV) proteins (including mAbs against viral proteins expressed on the surface of infected cells (neutralising Ab capacity), structural and non-structural CMV proteins with an emphasis on viral proteins involved in immunoevasion functions and viral MHC I-like proteins for studies in structural biology);
  • generation of mAbs to other immunologically important targets (mAbs against viral chemokines and cytokines, mAbs to several proteins expressed on human NK cells, potential markers on pancreatic tumor, neuro-stem cells);
  • custom mAbs/hybridoma development;
  • development of novel immunotherapeutic approaches to treat viral infections based on fusion proteins consisting of anti-viral mAbs and soluble ligands for different lymphocyte receptors.

Techniques available

  • Protein immunogen expression and purification
  • Production of murine mAbs
  • mAb purification (HPLC, 5mg scale, adaptation to serum-free media)
  • mAb fragmentation
  • Ab characterization (western blot, immunoprecipitation, ELISA, flow cytometry, laser scanning, confocal microscopy, immunohistochemistry)
  • Mycoplasma testing
