Particle counts and examples of particle morphologies for shock treated 1 mg/mL antistreptavidin (A,B), 35 mg/mL antistreptavidin (C,D), and 1.75 mg/mL human growth hormone (E,F). The black portion of each bar represents particles with diameters at least 2 microns and less than 3 microns, the dark grey portion represents particles with diameters at least 3 microns and less than 5 microns, the light grey portion represents particles with diameters at least 5 microns and less than 10 microns, and the white portion represent particles with diameters at least 10 microns. Each bar represents the particle count from one vial.
