Overview
OpenSPR is the world’s only benchtop surface plasmon resonance (SPR) instrument. It provides high quality, label-free interaction analysis for a fraction of the cost of existing solutions. Our unique nano-structured sensor surface uses localized SPR (LSPR) to deliver repeatable, highly sensitive kinetic data.
Compatible Molecules:
- Proteins
- Peptides
- Antibodies
- Antibody variants
- Nucleic acids
- Lipids
- Adeno-associated viruses (AAV)
- Virus-like particles (VLPs)
- Hormones/cytokines
- Small molecules (application dependent)
Supported Assays:
- Kinetics/affinity characterization
- Concentration analysis
- Yes/No binding
- Competition assays
- Epitope mapping
