| molecularNote | The targeting vector was designed with (from 5' to 3')a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter (from pCAGGS), an frt-flanked STOP cassette (with a short open reading frame, followed by translational stops in all three reading frames, a synthetic polyA sequence, a polyA sequence from the human growth hormone gene, and a polyA sequence from the Herpes Simplex Virus TK gene), a loxP-flanked STOP cassette (with stop codons in all three reading frames linked to three repeats of the SV40 polyA signal), a sequence encoding the CatCh/EYFP fluorescent protein, a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE; to enhance the mRNA transcript stability), a bovine growth hormone polyA signal, an AttB site, a PGK promoter-Neomycin resistance gene-PGK polyA cassette, and an AttP site. This entire targeting vector was inserted between exons 1 and 2 of the Gt(ROSA)26Sor locus. Chimeric female mice was bred to mice expressing Gt(ROSA)26Sortm3(phiC31*)Sor to remove the AttB/AttP-flanked PGK-Neo-polyA cassette and replace it with the recombined AttB/AttP site (AttL). |
