Lysine dendrons that possess N-terminal alkyne residues at the periphery were quantitative functionalized with azido peptides using click chemistry. The solid-phase peptide synthesis (SPPS) allows preparing the peptide dendron in high purity and establishing the possibility of automation. The presented peptide dendron is a promising candidate as multivalent ligand and was used for antibody B13-DE1 recognition. The binding affinity increases with higher dendron generation without loss of specificity. The analysis of biospecific interaction between the synthesized peptide dendron and the antibody was done via surface plasmon resonance (SPR) technique. The presented results show a promising tool for investigations of antigen-antibody reactions.}, language = {en} } @article{HovestaedtMemczakPleineretal.2014, author = {Hovestaedt, Marc and Memczak, Henry and Pleiner, Dennis and Zhang, Xin and Rappich, Joerg and Bier, Frank Fabian and St{\"o}cklein, Walter F.

Therefore, a FITC mimotope peptide (MP1, 12 aa), a human mucin 1 epitope peptide (MUC, 9 aa) and a protein with their specific antibodies were used as model systems. The peptides were modified with an N-terminal cysteine for covalent and directed coupling to the maleimido functionalized surface by means of Michael addition. The coupling yield of the peptide, the binding characteristics of antibody and the unspecific adsorption of the analytes were investigated. The results expand the spectrum of biosensors usable with p-MP by widely used SPR and support its potential to be versatile for several electrochemical and optical biosensors. This allows the combination of an electrochemical and optical read-out for a broad variety of biomolecular interactions on the same chip.
