... of the Drosophila homeoprotein Antennapaedia (residues 43–58, commonly named penetratin, RQIKIWFQNRRMKWKK), also provide novel insights into the fundamental mechanisms of translocation across biological membranes. Thus the efficacy of CPP-mediated cargo delivery continues to provide valuable tools for biomedical...

... anionic molecules in vivo . A potential approach to solving this problem is the chemical conjugation of siRNA to the cationic CPPs (cell-penetrating peptides), Tat-(48–60) (transactivator of transcription) and penetratin, which have been shown previously to mediate protein and peptide delivery in a host...
