摘要

Grating-coupled interferometry (GCI) is a biophysical method suitable to studying the binding kinetics of protein–ligand interactions. Here, we describe the application of biotinylated inositol pyrophosphate (PP-InsP) nutrient messengers to characterize PP-InsP–protein interactions using a Creoptix WAVEsystem.
