Affinity and kinetics of
extracellular vesicles – protein interaction

Application Note #164

 

Extracellular vesicles (EVs) are extensively studied as potential therapeutics, drug delivery systems and for non-invasive diagnostics of diseases, such as cancer. Early detection of ovarian cancer was explored using Multi-Parametric Surface Plasmon Resonance (MP-SPR) instrument. Tumor EVs (SKOV-3) were loaded onto surface-immobilized LXY30 peptide. Affinity and kinetic constants of the interaction, bound mass and layer thickness
were determined based on MP-SPR measurement. LXY30 peptide exhibits a high affinity to EVs expressing α3β1 integrin and offers possibility for diagnostic applications.
