    摘要: This invention relates to a method for enhancing the production of biologically active proteins and peptides in bacterial cells by infecting bacterial cells of the producer strain, which contain a plasmid with one or more targeted genes, with bacteriophage &lgr; with or without the targeted gene(s). The targeted genes encoding the biologically active proteins are under the control of a T7 polymerase promoter and the bacteria also are capable of expressing the gene for T7 RNA polymerase. The phage increases synthesis of the targeted protein and induces lysis of the producer strain cells. Super-production is achieved by the combination of the high level of expression achieved from the T7 polymerase promoter and by cultivating the producer strain cells under culture conditions that delay lytic development of the phage. The biologically active proteins and peptides subsequently accumulate in a soluble form in the culture medium as the cells of the producer strain are lysed by the phage.

    摘要: A composition for in vitro and in vivo transfection of vertebrate male germ cells comprises a nucleic acid or transgene, and a gene delivery system, and optionally a protective internalizing agent, such as an endosomal lytic agent, a virus or a viral component, which is internalized by cells along with the transgene and which enhances gene transfer through the cytoplasm to the nucleus of the male germ cell. A method of genetically altering a vertebrate male germ cell in vivo employs a lentiviral-derived vector. A method of substantially depopulating a vertebrate testis employs a combination of a dose of an alkylating agent, such as busulfan, chlorambucil, cyclophosphamide, melphalan, or ethyl ethanesulfonic acid, and a dose of gamma radiation. A pharmaceutical preparation and a transfer kit utilize the composition. A method for introducing a polynucleotide into vertebrate male germ cells comprises the administration of the composition to a vertebrate. A method for isolating or selecting transfected cells utilizes a reporter gene, and a method for administering transfected male germ cells utilizes male germ cells which have been transfected in vitro.
