| molecularNote | Two individual targeting vectors were used to place a loxP site (and an Frt1-flanked PGK-neo cassette) upstream, and a loxP site (and an Frt5-flanked puromycin resistance/TK cassette) downstream of the Snord116 cluster. The upstream targeting vector was transfected into C57BL/6-derived Bruce-4 embryonic stem (ES) cells, and correctly targeted ES cells were next transfected with the downstream targeting vector. Doubly targeted ES cells were then transiently transfected with a cre expressing plasmid. The resulting 1-loxP ES cells (with the Snord116 cluster deleted and a single loxP site remaining) were injected into recipient blastocysts. |
