Depositor Comments

Alternate plasmid name: K15-LacZ-pCMVβ

The K15 promoter was cloned from C57 BL/SJ mouse genomic DNA (isolated from tail) by PCR using the Supermix High Fidelity Kit (GIBCO). The sequences of the forward and reverse primers were


respectively. XhoI and EcoRI restriction sequences were added to the 5' end of forward and reverse primers respectively for subsequent cloning of the PCR product into PBK/CMV vector (Stratagene). The promoter fragment was then subcloned into pCMVβ (Clontech).

The entire K15 promoter-lacZ transgene can be released by digestion with XhoI/SalI.
