Gfra1^{tm1.1(cre/ERT2)Cfi}

The targeting vector using bacterial artificial chromosomes (BACs) from the C57BL/6J RPCIB-731 BAC library was constructed by inserting a CreERT2 cassette and F3 flanked puromycin resistant cassette into the second exon of the Gfra1 gene in frame. The vector was transfected into the TaconicArtemis C57BL/6N Tac ESC line to establish mouse line by homologous recombination. Flp-mediated recombination removed the F3-flanked puro cassette.
