Western blots showing the presence of Shr-specific antibodies in convalescent sera from patients of streptococcal pharyngitis. Purified Shr (50 ng/lane) was resolved by SDS PAGE and analyzed by Western blotting using convalescent sera from three pharyngitis patients (lanes 1–3) and a person without S. pyogenes exposure as negative control (lane 4).
