Abstract: Disclosed is a host cell for producing a recombinant peptide, polypeptide or protein of interest, wherein the host cell includes at least 2 copies of a nucleic acid sequence encoding a poison protein; and to the use thereof for producing peptides, polypeptides or proteins of interest.

Abstract: Methods are disclosed for generating antibodies and an expression vector used to express protein(s) which provoke the antibody response. The expression vector may be useful in generating an antibody directed to an antigen, comprising a gene in operable linkage with a promoter, which gene encodes upon expressing a fusion protein comprising (i) CD134L, a fragment, homologous or orthologues protein thereof as N-terminal moiety of the fusion protein; and (ii) all or part of an antigenic protein as C-terminal moiety of the fusion protein. To generate the antibodies, the vector is injected into a subject animal, which produces a fusion protein, against which antibodies are generated.

Abstract: The present invention relates to a genetically modified phage and use thereof in a method for producing a biomolecule of interest.

Abstract: The present invention is related to integrated method and tools to construct recombinant DNA molecules (to be used as DNA vaccine or gene therapy) without requiring the use of antibiotic(s) resistance gene(s) and without requiring the addition of one or more antibiotic(s) to the culture medium of cells submitted to this recombinant DNA method. The present invention allows to obtain the selection of recombinant host cell(s) transformed by a (exogenous) nucleic acid sequence of interest (extra-chromosomal vector containing the insert) and simultaneously stabilization (stable inheritance) of this (exogenous) nucleic acid sequence of interest into the transformed host cell(s) descendants (maintenance of the nucleic acid sequence of interest in the host cells population).

Abstract: The present invention is related to a reversible, parallel and/or multitask cloning method and kit, which improve the cloning of (preferably multiple) genetic element(s) in a nucleic acid construct such as vector or in chromosome of a cell and the rapid and efficient selection of said construct with a correct integration of said genetic element(s) either in vitro or in vivo.

Abstract: The present invention is related to a recombinant eucaryote cell or organism having incorporated in its genome a genetic construct made of at least one nucleotide sequence encoding a toxic gene (TOX) under the control of an inducible promoter/operator genetic sequence and possibly a selectable marker. The present invention is also related to a production and selection method-of-genetically modified eucaryote cells or organisms having integrated into their genome foreigner (exogenous) DNA fragment(s) by using said recombinant eucaryote cells or organisms.
