| molecularNote | The pTRE2-LSL-GCaMP6s-CAG-LSL-tdTom-tTA2 replacement vector designed with (from 5' to 3') an frt3 site, two copies of chicken beta-globin HS4 insulator element (to reduce reporter gene expression in absence of transactivators), a Tet response element/promoter (TRE2), a loxP-flanked STOP cassette (stop codons in all three reading frames linked to synthetic pA-hGHpA-PGKpA), a GCaMP6 slow variant calcium indicator sequence (GCaMP6s), a WPRE (to enhance the mRNA transcript stability), 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 (stop codons in all three reading frames linked to synthetic pA-hGHpA-TKpA), tdTomato sequence, a porcine teschovirus-1 2A, self-cleaving peptide (P2A), a synthetic modified tetracycline-regulated transactivator gene (tTA2(S)), a WPRE, a BGH polyA, an AttB site, a PGK-5'hygro cassette, an RNA splice donor and a frt5 site was inserted into the T1 TIGRE locus (an intergenic region on chromosome 9 [between AB124611 and Carm1] determined to have low basal transcriptional activity and allow high Cre and/or Tet inducibility). PhiC31 recombinase removed the AttB/AttP-flanked PGK-hygro-SV40polyA cassette and replaced it with the recombined AttB/AttP site (AttL). |
