Genetically synthesized antibody-binding protein self-assembled on hydrophobic matrix

초록

A unique antibody-binding protein, (E12B2)n, was genetically synthesized, which was characterized by a hydrophobic peptide, E12, at one terminus and an antibody-binding peptide, B2, at the other. It was clarified by atomic force microscopy (AFM) imaging that this protein was efficiently self-assembled on a hydrophobic solid surface. (E12B2)n self-assembled on a microplate exhibited an excellent performance of antibody-binding affinity. The proposed design of antibody-binding protein seems promising in immobilizing antibody molecules on hydrophobic solid surfaces.
