Abstract:Multivalent surface display of biomolecules is crucial to study and utilize multivalent biological interactions. However, precise valency control of surface‐displayed ligands remains extremely difficult. Now a series of new oligomeric avidin proteins were fabricated that allow facile control of surface multivalency of biotinylated ligands. Naturally dimeric rhizavidin (RA) was engineered to form a mixture of oligomeric avidin assemblies, and discrete RA oligomers from the dimer to octamer of RA, were homogeneo… Show more
