Streptococcus pyogenes Streptolysin O (slo)

Extracellular protein streptolysin O is a key virulence factor of group A streptococci and belongs to the beta-barrel pore-forming exotoxin family called thiol-activated cholesterol-dependent cytolysins (CDCs). After secretion, it binds to the host erythrocyte membranes forming ring-like structures. The presence of cholesterol in the target membrane is required for pore formation which finally results in cytolysis. DIARECT™ antigens are for further manufacturing or research use only.
