We aim to identify the ligand of a receptor, but due to the low affinity of the interaction other approaches that have been tried failed. Paul Helbling and the DualSystem team provided a great support and critical insights for performing the ligand identification using the LCR-TriCEPS technology. We found now a candidate ligand that we are currently validating with promising results. DualSystem team has been really professional and of great support in this process and we plan to work again with them in the future.
