| description | This exchange vector (along with the pDIRE plasmid containing an icre-expression cassette and a Flpo-expression cassette to facilitate insertion of the exchange vector) was electroporated into C57BL/6N-Atm1Brd-derived JM8A3.N1 knockout first reporter embryonic stem (ES) cells obtained from the European Conditional Mouse Mutagenesis (EUCOMM) consortium containing clone EPDO558_1_A04). Recombined ES cells, with the neo removed and resistant to puro, were injected into B6(Cg)-Tyrc-2J/J blastocysts and resulting chimeric mice were bred to C57BL/6J to establish a colony. Recombined ES cells, with the neo removed and resistant to puro, were injected into B6(Cg)-Tyrc-2J/J blastocysts and resulting chimeric mice were bred to C57BL/6J to establish a colony. |
| molecularNote | The allele was generated by a dual recombinase-mediated cassette exchange protocol. The exchange vector contained (from 5' to 3') an frt site, a viral F2A oligopeptide (to mediate ribosomal skipping), an enhanced green fluorescent protein (EGFP) sequence, a viral T2A oligopeptide, and a cre/ERT2 sequence. A rox-flanked puromycin resistance (puro) cassette and a loxP site were inserted at the 3' end of the exchange vector. |
