title: Binding of small peptides to immobilized antibodies: kinetic analysis by surface plasmon resonance.
abstract: This unit describes a method for screening small viral peptides as specific antigens using a surface plasmon resonance (SPR) biosensor. The basic protocol in this unit is suited for direct single-step SPR analysis of small ligand-large receptor interactions, where small peptides are used as analytes (injected in the continuous buffer flow) and monoclonal antibodies (MAbs) are immobilized on the SPR sensor chip surface. An alternate protocol is included for situations where kinetic analysis is not possible and uses a surface competition assay to indirectly measure the kinetics of small analyte binding.
