Antibody-analyte interactions were evaluated with an Octet RED96 biolayer interferometry instrument (Molecular Devices, Sartorius AG, Göttingen, Germany). All measurements were performed in 96-well microplates (Greiner Bio-one, Frickenhausen, Germany) at ambient temperature. Antibodies were loaded at 25 nM in 1× Kinetics Buffer for 120 seconds and captured using AMC tips for mouse antibodies, AHC tips for humanized recombinant antibodies, and Protein A tips for rabbit antibodies. Materials for the Octet were purchased from Molecular Devices. New sensors were used for every reaction and no tip regeneration was performed.
