Abstract

Summary

In rabbit antisera to staphylococcal δ haemolysin the haemolysin-neutra-lising activity was associated with the IgG fraction as well as with the α and β lipoproteins. On an equal-weight basis, the neutralising capacity of specific antibody was not significantly greater than that of serum α or β lipoproteins. Anti-α haemolysin was not detected in any of the anti-δ-haemolysin antisera. Amino-acid analysis of δ haemolysin showed that lysine, aspartic acid, threonine and isoleucine were the predominant amino acids present; histidine, arginine, proline, cysteine and tyrosine were absent. The molecular weight of δ-haemolysin in phosphate-buffered saline was approximately 210 000.
