A fast and reliable characterisation of protein-protein interactions is essential for various applications in both academic research as well as the chemical and pharmaceutical industry. Label-free technologies do not require a labelling with a reporter substance and enable a real-time monitoring and the determination of kinetic parameters. Many label-free biosensor systems however suffer from a low throughput read-out.

Biametrics’ SCORE technology (single colour reflectometry) enables now the unique combination of label-free measurements with high throughput screenings. We recently characterised the binding of an anti-FLAG antibody to a high density peptide array of FLAG epitope variants. 1485 antibody-antigen interactions were thereby detected simultaneously and a full kinetic evaluation was performed for each interaction.
