Abstract: Herein is reported a composition for the targeted delivery of large nucleic acids to the nucleus of a eukaryotic cell comprising non-covalent complexes of histones in form of assembled nucleosomes, a large nucleic acid, a hapten, and a bispecific binder that has a first binding specificity to the hapten and a second binding specificity to a cell-surface target present on the eukaryotic cell, wherein the histone and/or the nucleic acid is/are covalently bound/conjugated to the hapten, the histone and the large nucleic acid are associated (non-covalently) with each other/form a non-covalent complex, and the hapten and the bispecific binder are associated with each other/bound to each other by the first binding specificity of the bispecific binder.

Abstract: Herein is reported a method for the recombinant production of a polypeptide in a eukaryotic cell comprising the steps of (i) cultivating a eukaryotic cell comprising a nucleic acid encoding the polypeptide in a cultivation medium comprising a compound selected from the group consisting of trans-2-methyl 2-pentenoic acid, the broad-spectrum HDAC inhibitor Quisinostat, and the subtype-specific HDAC inhibitor Romidepsin, and (ii) recovering the polypeptide from the cell or the cultivation medium and thereby producing the polypeptide in a eukaryotic cell.

Abstract: 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.
