rSLO (streptolysin O)

Streptolysin O (SLO) is a single polypeptide chain that is not glycosylated. It has a molecular mass of ∼69 kDa and an isoelectric point (pI) of 6.0-6.4. Streptolysin O is an immunogenic, oxygen-labile toxin, which is reversibly activated by dithiothreitol. It is released into the extracellular medium along with other toxins, including streptolysin S, during the growth of most strains of group A and many strains of groups C and G Streptococci
