Mice that are hemizygous or homozygous for this transgenic insert are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the human keratin 14 (<i>KRT14</i>) gene promoter (active in embryonic and postnatal basal cells of the skin). When mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (tetO), expression of the target gene may be regulated by the tetracycline analog, doxycycline (dox); in the presence of dox, transcription of the target gene is induced in cells where rtTA is expressed. This strain provides a Tet-On tool that allows the inducible expression of genes in cells expressing KRT14 for hair and skin research. 

This transgenic strain provides a Tet-On tool that allows doxycycline (dox) inducible expression of genes in cells where the human KRT14 promoter is active and may be useful in applications for hair and skin research.

Typically mice are recovered in 12-16 weeks. Contact Customer Service to place an order or for more information.
