Extended Data Fig. 9: TEM images of S-R1-R2-H in the dual-spring DNA device.
From: DNA nanodevice for analysis of force-activated protein extension and interactions

The four groups of images show proteins in the relaxed (L-/R-) and various extended conditions (L+/R-, L-/R+ , L+/R+ ). L/R denotes the left/right springs and -/+ denotes the loaded/activated states. Scale bars for zoomed-in and zoomed out images are 50 and 100 nm, respectively.
