Previously, we reported the synthesis of a biotin-dopamine conjugate (Btn-DA) with a photocleavable 8-quinolinyl benzenesulfonate (QB) linker for the isolation of an intact complex of DA and anti-DA antibody (IgG1) (DA-IgG1 complex). In this work, we synthesized a photocleavable Btn-DA conjugate with a polyethyleneoxy linker to improve the complexation efficiency and the recovery yields of DA-IgG1 complex. The results of QCM, ELISA, and Western blot analyses indicate that the introduction of polyethyleneoxy linkers improved the efficiency of DA-IgG1 complexation.
