Query: Glucagon stop-go kinetics supports a monomer-trimer fibrillation model   We investigate in vitro fibrillation kinetics of the hormone peptide glucagon
at various concentrations using confocal microscopy and determine the glucagon
fibril persistence length $60 \mu\textrm{m}$. At all concentrations we observe
that periods of individual fibril growth are interrupted by periods of stasis.
The growth probability is large at high and low concentrations and is reduced
for intermediate glucagon concentrations. To explain this behavior we propose a
simple model, where fibrils come in two forms, one built entirely from glucagon
monomers and one entirely from glucagon trimers. The opposite building blocks
act as fibril growth blockers, and this generic model reproduces experimental
behavior well.
