title: Absence of nephritis strain-associated protein (NSAP) in the extracellular product of Streptococcus pyogenes strain Su.
abstract: This study was undertaken to ascertain whether or not a nephritis strain-associated protein (NSAP) is produced by Streptococcus pyogenes strain Su, which is used in OK-432, an antitumor agent. SDS-PAGE and double immunodiffusion analysis showed that no NSAP occurred in the extracellular product of S. pyogenes strain Su.
