Patent ID: 7534857

Claim:
A biologically pure RNAIII inhibiting peptide (RIP), comprising: (a) five contiguous amino acids of the sequence YX 2 PX 1 TNF, where X 1 is C, W, I or a modified amino acid, and X 2 is K (SEQ ID NO: 1) or S (SEQ ID NO: 2); or (b) an amino acid sequence that differs from the sequence YX 2 PX 1 TNF by two substitutions or deletions, where X 1 is C, W, I or a modified amino acid, and X 2 is K or S, wherein the RIP does not consist of the sequence YSPX 1 TNF where X 1 is C, W, I, or a modified amino acid, wherein the RIP comprises the amino acid sequence YKPX 1 TNF.
