Analytical ultracentrifugation for the determination of the PE, PilA, and PE-PilA size in solution. The molecular weight (MW) of the monomer (MWmono) is indicated as an inset in each profile. Consequently, it is also indicated whether the molecule is in monomeric or dimeric form in solution. c(M) is a coefficient that reflects the molecular weight distribution.
