Using LRC-TriCEPS, we aimed to identify novel direct cell surface receptors of our ligand of interest.
At any time, we experienced great support of Dualsystems Biotech. They kindly helped to find optimal conditions for our purposes and provided help with any kind of question before, during and after the experiment. LRC-TriCEPS allowed us to identify novel cell surface receptors of our ligand, which we could successfully validate in different cell types and with different biochemical assays. We can fully recommend Dualsystems Biotech and are looking forward to perform further analyses using LRC-TriCEPS.

We appreciate the support of Dualsystems Biotech and their LRC-TriCEPS technology we were able to identify a binding protein for our>INSotropic peptide

We wanted to use LRC-TriCEPS to characterise the mechanism of action of our ligand of interest. Not only were several candidate targets identified but we have successfully validated two of these receptors in>INS producing beta cells. DualSystems Biotech were very helpful and involved from study design, to experiments and reporting. Even after the initial report, DualSystems Biotech have answered follow up queries and provided assistance regarding publications. I highly recommend the LRC-TriCEPS technology and DualSystems Biotech and Paul Helbling and his team to work with.

“We had a challenging project where we aimed to discover the receptor of our ligand of interest in primary human cells. Dualsystems Biotech took the challenge and provided outstanding support throughout the entire process, from the experimental design to data analysis. Using their LRC-TriCEPS technology, we could identify a candidate receptor and additional downstream interacting partners that we have now validated. We look forward to new collaborations and discoveries with Dr Paul Helbling and his team”. – Prof Carola Vinuesa, ANU

We used DualSystems to help identify a potential novel receptor for a ligand that despite being studied for decades had unclear catabolism mechanisms involving its receptor mediated uptake. The DualSystems team will walk you through the process, including early validation of your ligand being used for this technology, data collection and analysis, and provide an easy to follow report on the findings. For anyone interested in receptor-ligand interactions, DualSystems and the TriCEPS approach is worth strongly considering involving in your research program, as it can quickly help identify receptors that would have been very difficult to do so without.

“It was my great pleasure to collaborate with Dualsystems Biotech. We have been tested various proteomic analysis to identify the specific receptor for our secreted ligand. But, only LRC-TriCEPS experiment successfully gave us a right answer, because this receptor and ligand interactions were indeed relatively weaker than other general receptor and ligand interactions. The team very kindly consulted the whole experimental steps from the experimental design to the final data analysis. We are now going to use TriCEPS  again for several other secreted ligands with a great hope for discovery of new receptors. Best Regards, Ho Min Kim”

We were fortunate to partner with Dualsystems Biotech AG to discover cell-surface targets for the short-peptide ligand we had been working on for several years. We decided to try the LRC-TriCEPS approach to identify cell-surface binding partners for the ligand after several earlier aborted attempts using different techniques. Using LRC-TriCEPS we have identified targets that we have now been able to verify functionally and biochemically using other methods. It was a pleasure to work with Dr Paul Helbling and his team who were extremely helpful guiding us through the experimental process and assisting with analysis of the data. We were impressed by the quality of the data and the ease with which we were able to run the study.

“I have used many binding assays and was in the verge of giving up. Then I have contacted Dr. Paul Helbling and his group. The LRC-TriCEPS experiment was effective and let us go over the obstacle we had during the project. We look forward to using TriCEPS in the future”.

I was very pleased with my collaboration with the team at Dualsystems. We had to work with difficult cells and the team helped us develop modifications to the original protocol to be able to use the TriCEPS approach with our cells. The whole team was very responsive, involved, and knowledgeable and this led to a successful identification of a receptor for our ligand of interest. We have since then confirmed the interaction and we are now getting ready to publish this study, which will have implications in the treatment of ocular injuries.
