The line was obtained by microinjection of a circular murine BAC transgene (RP23-336D20) previously modified by recombineering at the ATG of the Krt10 gene of a rabbit-beta-globin intron-cre/ERT2 cassette followed by a flipped PGK-Tn5-Kana/NeoR cassette. The subline 39.28 was analyzed and cryopreserved. (J:82809)
