New technology platforms to identify new protein-protein interactions at the cell membrane
Dualsystems the experts for protein-protein interactions at the cell membrane
Dualsystems Biotech AG is specialises in elucidating protein-protein interactions in the living cells especially at the cell membrane. Dualsystems is a privately held service provider company based in Schlieren (Zurich), Switzerland. Our clients range from big pharma, biotech to academia. We focus on our conceptually new technology for target deconvolution on the Ligand-Receptor Capture LRC-TriCEPS platform. The LRC-TriCEPS technology is able to identify the unknown targets, off-targets, receptors of your orphan ligand on the living cells and is an excellent tool to investigate the binding partners of your drug candidates.
Following orphan ligands can be used: small molecules, peptides, proteins, antibodies, viruses.
LRC-TriCEPS – Ligand-receptor capture Service
Identification of the targets and off-targets at the cell surfaces of living cells
Ligand-receptor capture technology LRC-TriCEPS. A novel LC-MS/MS based approach to identify the cell surface receptors and off-targets for a ligand of interest after protein-protein interaction on the living cell. The LRC-TriCEPS technology was invented by Dr. Andreas Frei and Prof. Bernd Wollscheid from the ETH Zurich who published the technology in Nature Biotechnology (Frei et al.(2012) Nature Biotechnology 30:997-1001).
Now a new Version of TriCEPS is available.

Flow TriCEPS Services/Kit
Cell selection and optimisation of binding conditions for target identification
Identification of the targets using TriCEPS V2.0 in or at the cell membrane of your ligand (peptide, protein, Antibody, ADC or other primary amine containing molecules) requires that the cells used are expressing the unknown targets. TriCEPS V2.0 is the ideal tool to screen cell lines or primary cells to identify the best cells to use later in the LRC-TriCEPS target identification experiments. Dualsystems offers these pretests for cell selection as service and kit. Needed for the experiment is the ligand of interest and the cell lines/ primary cells that are expected to express the unknown target. There is no need for a ligand specific antibody.
Flow (Pretest) TriCEPS Service and Kit is available.
