    摘要: Provided are methods and compositions for delivering a nucleic acid, protein, and/or ribonucleoprotein payload to a cell. Also provided are delivery molecules that include a peptide targeting ligand conjugated to a protein or nucleic acid payload (e.g., an siRNA molecule), or conjugated to a charged polymer polypeptide domain (e.g., poly-arginine such as 9R or a poly-histidine such as 6H, and the like). The targeting ligand provides for (i) targeted binding to a cell surface protein, and (ii) engagement of a long endosomal recycling pathway. As such, when the targeting ligand engages the intended cell surface protein, the delivery molecule enters the cell (e.g., via endocytosis) but is preferentially directed away from the lysosomal degradation pathway.

    摘要: Herein is reported a method for determining the introduction of a nucleic acid into the genome of a mammalian cell, whereby the mammalian cell comprises one or two transcriptionally active alleles of a DPH1, DPH2, DPH4 and/or DPH5 gene, comprising the steps of transfecting the mammalian cell with one or more plasmids comprising the nucleic acid to be introduced, and the elements required for gene editing of said DPH gene, cultivating the transfected cell in the presence of a DPH gene transcription sensitive toxin, and thereby determining the introduction of a nucleic acid into the genome of the mammalian cell if the transfected cells is viable in the presence of the toxin.

    摘要: A molecular complex comprising a therapeutic agent and a controlled release construct, the controlled release construct comprising a primary matrix conjugation site which is linked to an cell adhesive site, via a binding region and optionally via one or more spacer elements, wherein the binding region has a folded configuration in which it is bound to the therapeutic agent, wherein the construct is configured such that when mechanical tension is applied between the primary matrix conjugation site and the cell adhesive site, the binding region adopts a less folded configuration in which bound therapeutic agent is released. Related controlled release constructs for loading with the therapeutic agent, pharmaceutical compositions and methods of manufacture and use.
