Further shortening of the link protein gene promoter reveals in vivo X-gal staining in the limb and genitalia. (A). Two link protein gene promoter regions −690 and −315 were studied in transgenic mouse lines. (B) Representative E15.5 mouse expressing the −690 promoter shows intense X-gal staining in the limb and genitalia. (C) Similarly, E15.5 mice expressing the −315 promoter also showed intense X-gal staining in the limb and genitalia with additional expression in the epidermis. Boxes indicate genitalia.
