Effects of various forms of agitation on the growth of β2m amyloid fibrils at 100 (A) and 1000 (B) mM NaCl monitored by measuring light scattering at 350 nm. The solutions of β2m were agitated with a stirring magnet or irradiation with ultrasonication pulses. The effects of seeding were also examined. Light scattering intensity at 350 nm was monitored as a function of time. For comparison, the kinetics under quiescent conditions are also shown. When the effects of ultrasonic pulses or seeding were examined, the solutions were stirred.
