Abstract:
Methods and vectors are provided for the specific alteration of particular genetic loci in eukaryotic cells. One method includes the utilization of positive-positive selection (PPS) DNA vectors for the purpose of creating and identifying cells which have vector sequences integrated into the host cell genome via site-specific homologous recombination. The method also comprises the utilization of sequences encoding in vivo detectable markers for the identification of cells which have exogenous vector sequences integrated into the genome of the host cell, either via site-specific homologous recombination or nonhomologous recombination or insertion. The invention also includes vectors for creating modifications in eukaryotic cells.
