Biomolecular interaction studies

Overview

Real-time binding data is essential to understand the dynamic interactions between proteins and other biomolecules that drive and regulate biological processes. The OWLS system provides high-quality information-rich data required for comprehensive characterization of proteins and other molecules.

Applications notes
