Depositor Comments

The CRE-ER(TM) protein requires tamoxifen (TM) to catalyze LoxP site-mediated excision.

To generate the Ngn3 constructs, a 7.6 kb fragment containing Ngn3 (pGD15, contains the 6.5 kb upstream region of Ngn3) was isolated using Ngn3 cDNA to screen a mouse RPI-22 BAC library (Genetics Institute, Buffalo, NY). Three primers were used to fuse the Cre-ERTM-coding region to the Ngn3 ATG to generate a fragment that had part of the Ngn3 promoter and the 5' end of the recombinase. The primers used are p73 (5'-acacttgactccttgatcgctg-3'), p71 (5'-gttgcatcgaccggtaatgca-3') and p74 (5'-ttttcccaaccgcaggatgtccaatttactgaccgtacac-3'). This fragment was subsequently digested with ApaI and AgeI and ligated to the KpnI (blunt-ended)-ApaI (partial digestion)-digested pGD15, and a 2.4 kb AgeI-SacII (partial digestion, blunt-ended) fragment of pGD35. The insert from the final construct (pGD29) was released by NotI digestion.
