WebSep 14, 2024 · In this study, we combined computer simulations and FCS experiments to propose an FCS diffusion law for membrane binding. First, we generated computer simulations of spot-variation FCS (svFCS) measurements for a membrane binding process combined to 2D and 3D diffusion at the membrane and in the bulk/cytosol, respectively. WebThe FCS diffusion law intercept ( τ0) quantitatively describes obstructed diffusion in these cases. The τ0 is positive for transient trapping or clustering and negative for meshwork compartmentalization. The magnitude of τ0 for domain confinement increases with confinement size, confinement time, and partitioning into the domains.
