signal sequence called loxP, and can delete genes which are flanked by two loxP sites in the same direction. Selectable Marker, dT40 Cell. Subsequent deletion of the expression cassette by Cre induction will lead to a complete gene knock-out. A tightly regulated Cre recombinase, MerCreMer is designed as a fusion protein of Cre and the hormone-binding domains (HBDs) of the mutated estrogen receptor (Mer). Most of the transformants obtained in substrains Pasteur, Frappier, and Denmark resulted from homologous integration of the targeting vector (3'or 5 at the recA locus (Table 1 and Figure 1A ).

The mutant loxP system, which is composed of two different mutant loxP sites (loxP_RE and loxP_LE was first utilized for genetic manipulation of tobacco. Targeted integration of an expression cassette is also preferable over random integration, if the subsequent excision is intended. It is referred as an 'early strain' with regards to its genetic characteristics (regions of difference, insertional elements, antigen expression pattern). The plasmid resulting from this ligation was digested with Bgl II, and was ligated with the Bam HI cassette of -actin NeomycinR, -actin PuromycinR, -actin blasticidinR 16 to produce pLoxNeo, pLoxPuro and pLoxBsr, respectively. Lane 1, parental. In a second step, sucrose-selection is used to select for mutants that have undergone a second intramolecular recombination resulting either in inactivation of the recA gene or in reversion to wild-type. The chicken B cell line DT40 has been widely used as a model for gene knock-outs due to its high targeted integration activity. A.2-kb Apa I fragment from plasmid pEJ126 36 containing the.
