摘要:
The present invention features polypeptides comprising an amino acid sequence structurally related to SEQ ID NO: 1 and uses of such polypeptides. SEQ ID NO: 1 is a truncated derivative of a full length S. aureus polypeptide. The full-length polypeptide is referred to herein as full-length “sai-1”. A His-tagged derivative of SEQ ID NO: 1 was found to produce a protective immune response against S. aureus.
