| molecularNote | A conditional by inversion (COIN) intron consisting of a lox66_SA-Egpf-polyA_lox71 was inserted in the antisense orientation into exon 3 via homologous recombination, splitting exon 3 into 2 new exons (85 and 99 bp in length). The two lox sites are in reverse complementation orientation, thus cre-mediated recombination will irreversibly invert the inserted sequence. In addition, an FRT flanked drug selection cassette (hygromycin- or neomycin-delta-thymidine kinase cassette was inserted after the COIN intron. Flp-mediated recombination removed the drug selection cassette. |
