National Cancer Centre, Singapore
Prof Johnny Ong Chin-Ann, MD, PhD, Group leader
“We have been working together with ProteoGenix since 2020. Using phage display, they helped our team to develop several antibodies with effective blocking effects. We are pleased with their services and look forward to continue working together with them as we advance our research and bring the biologics to the clinical stage.”
Birmingham University, UK
Dr. Julie Rayes, Associate Professor
“I contacted ProteoGenix regarding the generation of monoclonal antibodies for the detection of a chemokine. ProteoGenix generated for us multiple monoclonal antibodies to detect the chemokine by ELISA, western blot and to test these antibodies in functional assays. They provided an excellent service, with regular updates, quick response to our queries and an excellent delivery of the product. I recommend their service for their efficacy and professionalism.”
Brown University, USA
Prof Jonathan Kurtis, MD, PhD, Chair, Department of Pathology and Laboratory Medicine
“I requested ProteoGenix’s services for the generation of antibodies against a malarial protein by phage display. Their naive human library, which is comprised of 368 donors, is a unique resource which was one of the criteria I used to select their company. They optimized their standard screening strategy to be able to identify two specific clones, that they then expressed with very high yields in their proprietary XtenCHO™ cell line. I highly appreciated their level of expertise and their commitment to go beyond expectations, and I would recommend them for their reactivity and the high quality of their services.”
Telum Therapeutics, Spain
Verónica Alcolea, Development Manager
“We are thrilled with the success we’ve achieved through our collaboration with ProteoGenix in developing monoclonal antibodies targeting our protein. The antibodies they produced were not only highly selective but also demonstrated exceptional affinity for our target, significantly advancing our research. ProteoGenix impressed us with their efficiency and speed throughout the process. Their commitment to providing excellent customer service made our experience even better, as they were always available to address our questions and concerns. We highly recommend ProteoGenix to anyone in need of high-quality antibody development.”
Canopy Immuno-Therapeutics, Israel
Dr. Galit Denkberg, Vice-President Discovery
“We contacted ProteoGenix to develop repertoires of specific antibodies against three antigens sharing high homology. As determined by ELISA, ProteoGenix developed several specific antibodies that exhibited no cross-reactivity with the other antigens. We appreciated their proactive approach to increase our chances of success (e.g., performing fusions at their own risks). We are satisfied with the services of the company.”
