| molecularNote | Sequence encoding the basic helix-loop-helix domain was disrupted by the insertion of a construct containing lacZ followed by a floxed neo cassette via homologous recombination. The neo cassette was excised by the transient transfection of targeted ES cells by cre recombinase. Expression of lacZ was visualized via Xgal staining. |
