The line was obtained by microinjection of a circular human BAC transgene (RP11-700M2) previously modified by recombineering at the ATG of the Krt5 gene of a rabbit-beta-globin intron-cre/ERT2 cassette followed by a flipped PGK-Tn5-Kana/NeoR cassette. The subline 40.10 was analyzed and cryopreserved. (J:82809)
