Three alphatype anti-idiotypic nanobodies were obtained from a naive nanobodies phage-display library. In the recent years, innovative biosensor developments have made several applications with rapid detection and high accuracy possible for real-time environmental monitoring, disease diagnostics and therapy [1,2,3,4,5,6,7].During the last decade, protein-basedor more particularly antibody-basedbiosensors are considered as the most commonly developed platforms [8,9]. Bacteriophages were purified from the culture supernatant by two successive precipitation steps with 4% PEG-8000, 500 mM NaCl. Multivalent nanobodies were either directly cloned into pHEN6, or first assembled in pBluescript II (KS) + cloning vectors lacking promoters by Gibson cloning . Nanobodies have been used in the clinic to overcome these problems because of the advantages of their easy expression and high level of stability. We develop CeVICA, a cell-free nanobody engineering platform that uses ribosome display for in vitro selection of nanobodies from a library of 1011 randomized sequences.
