Caption Generation of the Mir21atm1.1Zqy allele. (A) Diagram for Mir21a (miR21) exon 1-floxed targeting construct and location of primers used for genotyping of targeted locus and FLP, Cre-mediated excised targeted locus. The exon 1 of Mir21a and 3.2 kb, 5kb genomic fragments flanking exon 1 (left and right arm) were PCR-amplified and subcloned into a targeting vector such that exon 1 of Mir21a was followed by a neo cassette, and exon 1 was flanked by two loxP sites, neo was flanked by two FRT sites. This targeting construct was used to generate Mir21a flox/flox(neo) mice, which were crossed with FLP mice to excise the neo and generate the Mir21atm1.1Zqy allele (FLP-excised targeted locus). Mice can then be conditionally targeted by crossing with Cre-expressing mice to generate the Cre-excised targeted locus.
