| molecularNote | The gene coding region was deleted by homologus recombination. A beta-galactosidase gene was placed under control of the endogenous promoter. Successful recombination was confirmed by Southern blot analysis. Western blot analysis confirmed the absence of protein in adult mouse tissues. |
