Abstract: The present invention relates to a biological entity carrying a regulator construct comprising a specific repressor gene and a responder construct comprising at least one segment corresponding to a short hairpin RNA (shRNA) or corresponding to complementary short interfering RNA (siRNA) strands, said at least one segment being under control of a promoter which contains an operator sequence corresponding to the repressor. The invention further relates to a method for preparing said biological entity and its use.
Abstract: The present invention relates to a biological entity, notably a rat, carrying a regulator construct comprising a specific repressor gene and a responder construct comprising at least one segment corresponding to a short hairpin RNA (shRNA) or corresponding to complementary short interfering RNA (siRNA) strands or corresponding to miRNA, said at least one segment being under control of a promoter which contains an operator sequence corresponding to the repressor. The invention further relates to a method for preparing said biological entity and its use.

Abstract: The present invention relates to a process that enables constitutive and inducible gene knock down in living organisms using a short hairpin RNA expression vector integrated into the genome of the organism.
Abstract: The invention provides a method for targeted transgenesis using the Rosa26 locus. Suitable nucleotide acid sequences and vectors for the targeted transgenesis and recombinase mediated transgenesis are provided. The Rosa26 locus proved to be a suitable integration site allowing strong and predictable expression of inserted transgenes carrying exogenous promoters.
Abstract: The invention relates to a method that enables automated identification and isolation of cells harbouring a predetermined genetic modification (homologous recombination) using detectable/sortable markers, e.g. fluorescence markers, to identify homologous DNA modifications. Suitable vectors are also provided.
