Tg(Tff2-Hbegf,-cre/ERT2)#Tcw

Using recombineering methods, the DTR-CreERT2-FrtNeoFrt cassette was inserted at the ATG codon in exon 1 of the Tff2 gene in the BAC RP24-335C16. The modified BAC construct was injected into fertilized CBA x C57BL/6J oocytes. The modified BAC construct was injected into fertilized CBA x C57BL/6J oocytes. The pound symbol (#) is used when no line is specified and/or lines are pooled. (J:338908)
