Aggregation of fn-Δ50LA-TD in buffers with divalent cations. DLS-derived size distributions of 1 µM fn-Δ50LA-TD in 50 mM NaCl and 2 mM divalent cations as indicated. This result suggests that fn-Δ50LA-TD is a monomer in solution without divalent cations or when Ca2+ or Mg2+ are present in the solvent but aggregates in the presence of Mn2+ or Zn2+.
