CaptiRec Services detection of extracellular cell interactions 

A conceptual novel approach for ligand-receptor capture on the living cell

TriCEPS™-based ligand-receptor capture (LRC-TriCEPS™) is a novel technology. LRC-TriCEPS™ enables the unbiased identification of cell surface receptors and off-targets on the living cells without genetic manipulation. Ligand-receptor capture technology can be used for many types of orphan ligands, such as peptides, proteins, antibodies, engineered affinity binders but also for viruses.

Orphan ligands:

  • Extracellular proteins
  • Peptide ligands
  • Antibodies
  • Engineered affinity binders
  • Viruses

Dualsystems provides full analytical Services. After the method transfer a full LRC-TriCEPS™ Kit is available.
