The group of Professor Bernd Wollscheid from ETH Zurich showed in their latest publication that HATRIC-LRC (HATRIC Ligand Receptor Capture) enables the identification of the targets of a small molecule at the cell membrane of living cells to elucidate the mode of action of the molecule. Further, it was demonstrated that the HATRIC-LRC technology platform needs less cells for target identification than the previously published LRC-TriCEPS method and it enables the identification of N-, C-, and O- glycosylated targets.
Target identification using HATRIC-LRC is based on the trifunctional cross linker HATRIC that contains an NHS ester to couple the small molecule, a hydrazone to covalently bind to the carbohydrates of the unknown target proteins at the cell membrane and an azide as pull down function.
The small molecule is coupled to HATRIC using a primary amine. Either your small molecule contains already a primary amine or a primary amine is added by derivatization. In the next step cells expressing the unknown targets and off-targets are mildly oxidized and the HATRIC coupled small molecule is added. The small molecule binds its target(s) at the cell membrane and the second arm of HATRIC covalently binds to the carbohydrates of the target protein(s). During that interaction the cells are still alive. Then the cells are lysed, processed and the third arm of HATRIC is used to pull down the target proteins. Proteins are identified through bottom-up proteomics, relatively quantified and compared to one or several controls. The target candidates are those proteins that are enriched in the ligand of interest samples compared to the control treated samples since the ligand target interaction increases the likelihood of the target carbohydrates to covalently bind to HATRIC compared to the average cell surface protein. Controls can be a positive control such as transferrin or a negative control for example samples treated with an excess of the small molecule devoid of HATRIC prior to adding the HATRIC small molecule conjugate (competition).
Customers Testimonials – LRC-TriCEPS Service
Testimonials from our customers who have used the LRC-TriCEPS technology – in collaboration with Dualsystems Biotech AG.
AstraZeneca
We needed to identify the target of an antibody from a phenotypic screening approach using a difficult iPSC-derived cell line and reached-out to DualSystems and their LRC-TriCEPS technology after an earlier attempt at target deconvolution using an array of membrane targets had failed. The support I got from Paul Helbling and his team was great and as someone who was unfamiliar with the approach, I really appreciated the advice and guidance that I got. At the end of the process the top candidate from the analysis was confirmed as the target of the antibody – a brilliant result! Overall, a really positive experience and I would definitely recommend DualSystems.

DualSystems' LRC-TriCEPS platform was exactly what we needed to identify potential targets and guide us in mechanism of action studies for our peptide program. They helped us every step of the way -- from understanding their capabilities, to guiding study design, and supporting sample preparation. The report they delivered exceeded our expectations and truly stands out from data reports we've received from other companies. They were readily available to answer questions and discuss concerns or outcomes. We are very encouraged by the results and are currently following up on the targets identified. We highly recommend working with DualSystems and incorporating the LRC-TriCEPS platform into your program. We look forward to working with the DualSystems team again in the future.

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 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 insulin 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”

Department of Internal Medicine Erasmus MC
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 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.

The team from DualSystems Biotech AG has been extremely helpful in delivering scientific advice for CuroNZ’s target identification journey. The quick turnaround time and the precision of NRP2945’s target identification in regard to the utilization of their TRICEPS technology impressed us very much. Meanwhile we could identify another NRP2945 receptor target that was identified by DualSystems as being recruited to the NRP2945-activated membrane receptor complex. An absolute pleasure to work with Paul Helbling’s team.
