Patent ID: 8044019

Claim:
An isolated peptide having the capability of translocation to cells, wherein said peptide comprises the amino acid sequence shown below: B-X-Z-X-Arg-Z-Tyr-J-X-O 1 -X-Arg-O 2 -X-X or X-X-O 1 -Arg-X-O 2 -X-J-Tyr-Z-Arg-X-Z-X-B wherein (i) B is arginine or lysine, (ii) at least one of O 1 or O 2 is arginine, wherein, when one of O 1 or O 2 is arginine, the remaining O 1 or O 2 is an arbitrarily chosen amino acid, (iii) Z is a hydrophobic amino acid, (iv) J is serine or alanine, and (v) X is an arbitrarily chosen amino acid; with the proviso that when Z is leucine and O 1 is arginine, then J is alanine or B is lysine.
