experiment to demonstrate the utility of the new stack, I ran a series
of velocity clamp unfolding experiments on I27 octomers in PBS
(\cref{sec:sample-preparation}). After a series of pulls in the
-standard buffer, a buffer with additional sodium (from
-\NaCl\citep{bdh-NaCl}) or calcium (from \CaCl\citep{fisher-CaCl})
-was flushed into the fluid cell. After the new buffer equilibrated,
-unfolding experiments were continued.

Previous research on the effect of ions on unfolding forces is small,
although earlier experimental work on Amyloid $\beta$ shows decreased
