Fresnel-normalized x-ray interferometry data R(Qz)/RF(Qz) with regard to folding KvAP at the solid-liquid interface. (A) R(Qz)/RF(Qz) data for the organic self-assembled monolayer (SAM) used to tether the KvAP-DM monolayer to the surface of an Si-Ge-Si multilayer substrate are shown. (B) R(Qz)/RF(Qz) data for a KvAP-DM monolayer tethered to the surface of an Si-Ge-Si multilayer substrate are shown. (C) R(Qz)/RF(Qz) data for a KvAP-POPC membrane tethered to the surface of the same Si-Ge-Si multilayer substrate are shown. Error bars are based on the photon-counting statistics.
