    摘要: This disclosure provides a method of isolating peptides having cell-penetrating function, wherein the peptides are detected as biotinylated molecules only following their translocation through the cell membrane. The disclosure also provides methods for validating the cell-penetrating function of the peptides, or that may be employed in their own right to isolate such peptides, wherein the peptides are detectable by virtue of their ability to transport a detectable cargo into the cytoplasm, such as a cargo toxin or a fragment of a green fluorescent protein (GFP) that is required for complementation of a functional GFP. The disclosure also provides non-canonical peptides having cell-penetrating function that differ structurally from known CPPs such as TAT, VP22, transportan and penetratin, and that are capable of translocating cell membranes and escaping the endosome. The disclosed peptides have utility in transporting cargo therapeutics and diagnostics into cells.

    摘要: The present invention provides a method of determining or identifying or isolating a cell-penetrating peptide (CPP) or analog or derivative thereof having cell-type selectivity and/or at least capable of passing through a Blood Brain Barrier of an animal subject. This invention also provides CPPs and analogs and derivatives thereof, such as those set forth in SEQ ID NOs: 1-27 of the Sequence Listing, and compositions comprising one or more of the CPPs, including conjugates in which a CPP or analog or derivative thereof is linked to a cargo molecule. The invention also provides methods for transporting cargo molecules across cell membranes to specific locations within cells, and for treating, preventing and/or diagnosing diseases that are treatable by a cargo molecule to which a CPP or analog or derivative of the invention is attached. The invention also provides tailored peptide libraries for use in identifying or isolating CPPs.
