Microscopy from Scientific Research

Clipped phase-contrast HS-AFM images focusing on the fiber end in the 2.5 mM UC13 in EMI-Tf 2 N. Here, the time labels on the images indicate relative evolution time but do not mean the time elapsed since the molecule was injected. The yellow and blue arrows mark the positions of fiber ends during the pause phases prior to the onset of the growth phase. Scale bar: 30 nm. Imaging rate: 0.2 s/frame. See also Supplementary Movie 6. Representative images from time-lapse recordings of multiple independent experiments are shown.
