  • Publication number: 20060026706
    Abstract: Provided are multiple methods resulting in a site-specific, marker-less integration of a sequence of interest. The methods are based on the following: The genomic presence in a cell (host cell) of a selectable or screenable gene X. As a result of a mutation, this gene X can be essentially sensitive or insensitive to a certain component or condition Z or, as a result of a mutation in gene X, the host cell is made dependent on the presence of a certain component or condition Z; a plasmid on which the desired insertion (or deletion) is present, further harboring a truncated gene X and a selectable marker (such as an antibiotic-resistance gene) to select or screen for the presence or absence of vector sequences in the host cell; positive selection of the final recombination step, avoiding complicated and time-consuming screening for the desired recombinants. Preferably, both recombination steps are positively selected.
