molecularNote | The replacement vector is designed with (from 5' to 3') an FRT3 site, two copies of chicken beta-globin HS4 insulator element, a Tet response element/promoter (TRE2), a loxP-flanked STOP cassette, a synthetic enhanced green fluorescent protein sequence (EGFP), a woodchuck hepatitis virus post-transcriptional regulatory element, a BGH polyA, two copies of chicken beta-globin HS4 insulator element, a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter (CAG; from pCAGGS), a lox2272-flanked STOP cassette, a tdTomato sequence, a viral 2A oligopeptide that mediates ribosomal skipping, a synthetic modified tetracycline-regulated transactivator gene (tTA2S), a WPRE, a BGH polyA, an AttB site, a PGK-5'hygro cassette, an RNA splice donor and a FRT5 site. Embryonic stem cells previously targeted with FRT3::AttB::PGK-neoR-polyA::FRT5::splice acceptor::3'hygro cassette::SV40 polyA:AttP in TIGRE, were re-transfected with the pTRE2-LSL-EGFP-CAG-LSL-tdT-P2A-tTA2 replacement vector and Flp recombinase vector for recombinase-mediated cassette exchange (RCME). |
