The next generation of LRC-TriCEPS
Now available
TriCEPS v.3.0 enables receptor identification for your orphan ligands at the surface of living cells without genetic manipulation. Key features of the new TriCEPS v.3.0 and LRC- TriCEPS technology are:
- Reduction of the number of cells needed:
- TRICEPS v.3.0 LRC experiments require 5-10 fold less starting material for successful receptor identification compared to TRICEPS v.2.0.
- High coverage of the surfaceome.
- A modified LRC workflow enabled by TriCEPS v.3.0 allows for the theoretical identification of up to 85% of all putative cell surface proteins.
- Identification of N-, C-, O- glycosylated targets
More sensitive identification of low copy number cell surface receptors through whole protein pull-down.
Decoding the extracellular interactome using LRC-TriCEPS
Ligand-receptor capture
The LRC-TriCEPS technology was invented by Andreas Frei and Bernd Wollscheid from ETH Zurich who published the technology in Nature Biotechnology Nature Biotechnology (Frei et al.(2012) Nature Biotechnology 30:997-1001) and further developed it to HATRIC-LRC (Sobotzki et al. Nature Communications, volume 9, Article number: 1519 (2018) doi:10.1038/s41467-018-03936-z)
Orphan ligands:
- Extracellular proteins
- Peptide ligands
- Antibodies
- Viruses
- Engineered affinity binders

If you are looking for the targets of your ligand – peptide, protein, antibody, and virus – that are relevant in the living organism, call us on +41 44 738 50 00 or fill in the form on the right hand. We will contact you to see how LRC-TriCEPS technology (ligand-receptor capture) can answer your questions.
LRC-TriCEPS is a novel approach enabling the identification of cell surface receptors and off-targets on living cells for a wide range of orphan ligands. Advantages of LRC-TriCEPS compared to other approaches:
- No genetic manipulation
- No hypothesis needed
- Targets are embedded in plasma membrane in their natural microenvironment
- Cells are alive during interaction
Availability
The TriCEPS-based ligand-receptor capture technology is now available at Dualsystems.

Principle of LRC-TriCEPS
LRC-TriCEPS is a fast and sensitive approach to discover cell surface N-, C-, and O-glycosylated receptors for a ligand of interest.
- Label ligand with the TriCEPS chemoproteomic reagent
- Activate target cells or native tissue to oxidize cell surface glycans
- Incubate ligand-TriCEPS complex with activated cells
- TriCEPS immediately links ligand and cognate receptor(s)
- Isolate all membrane proteins with the support of TriCEPS
- Tryptic digest of all membrane proteins
- Identification of peptides by mass spectrometry
- Analysis of data using statistics and bioinformatics
LRC-TriCEPS – a trifunctional chemoproteomics reagent
TriCEPS structure:
- NHS-ester for attachment to the ligand
- Protected hydrazine function for capturing the interacting receptor
- Pull out function for purification of ligand-receptor peptides
Requirements
Requirements for one LRC experiment: Ligand in triplicate compared to control in triplicate
- 300 µg ligand containing a free amino group
- 60 Mio cells or 50 µm tissue slice

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.

The identification of a T cell co-receptor for staphylococcal superantigens had been challenging due to the structural features of the interaction and its kinetics. However, working with Dualstystems Biotech AG, and with Dr. Paul Helbling in particular, and using the LRC-TriCEPS technology, we were able to identify a candidate that was subsequently corroborated by biochemical and functional assays. We are very happy with this collaboration , and sincerely recommend it for the identification of novel receptor or co-receptor candidates.(Quim) Madrenas, MD, PhD, FCAHS
