Mussel adhesion is dictated by time-regulated secretion and molecular conformation of mussel adhesive proteins

We have a month with “R” again and the shellfish season has started in the Northern Hemisphere. So we’d like to share the Nature Communications article by Petrone et. al “Mussel adhesion is dictated by time-regulated secretion and molecular conformation of mussel adhesive proteins” with you.
A NanoWorld Pointprobe® NCSTR AFM probe was used for the AFM images in this paper. This AFM probe is designed to give extra stability and accuracy during soft tapping mode imaging in order to produce higher quality AFM images while minimizing sample damage.

Supplementary Figure 16 from Petrone et. al "Mussel adhesion is dictated by time-regulated secretion and molecular conformation of mussel adhesive proteins": Atomic Force Microscopy (AFM) of mussel adhesive proteins on mica. AFM images of dry Pvfp-3α and Pvfp-5β adsorbed from 0.02 mg ml-1 solution in 5% acetic acid and 0.25 MO3 on mica. After 20 min adsorption, the mica surfaces were washed with protein -free buffer, and the AFM images show the homogenous distribution of the resulting adsorbed proteins. The height profiles for both proteins are shown in the graphs below, corresponding to the dotted red and blue lines in the respective AFM images (see black arrows).
