| description | Embryonic stem cells (ES) NOG-ES was established and a clone a5363 was selected. |
| molecularNote | The Por exons 5-15 were flanked by FRT sequences by homologous recombination strategies using NOG-ES cells. The Puro drug-resistance marker gene was then removed from recombinant ES cells by transient expression of Cre recombinase. |
