Systematic Screening of Viral Entry Inhibitors Using Surface Plasmon Resonance

Surface plasmon resonance (SPR) analytical method was initially used as biosensor for analyzing diverse biomolecular interactions and recently gained important place in the drug discovery. Here, I describe the procedures for screening of inhibitors against the viral proteins using the SPR. Using the described procedures, in the past, we were able to identify several antiviral products that interfere viral-host receptor proteins interactions.
