Technical University of Munich – Institute of Experimental Oncology and Therapy Research 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. Prof. Dr. rer. nat.
