Available Strain Details

Strain Information
Common Strain Name: K5/tTA Pricing and Ordering Information
Strain Nomenclature: FVB/N-Tg(KRT5-tTA)1216Glk/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B1


Strain Description: The doxycycline-dependent transcriptional repressor, tTA, was placed under control of the bovine keratin 5 (K5, KRT5) promoter. When tested on a tetO-LacZ transgenic background, doxycycline suppressed expression of beta-galactosidase in a tissue-specific manner. Reduced beta-galactosidase activity was detected in skin (basal layer of the epidermis and hair follicles), tongue, forestomach, and trachea. No reduction was seen in tissues that do not express endogenous keratin 5 (liver, spleen, muscle, heart, intestine).
