Factors influencing PbA self-association. Interference SV experiments (50,000 rpm) on 1 mg/mL PbA in 140 mM salt solutions show peptibody self-association to have a strong dependence on the identity of the halogen anion, but not the alkali cation (Panel A). Self-association increased with NaCl concentration (0 and 200 mM) (Panel B) and with pH (Panel C).
