| molecularNote | A loxP-Frt-PGKneo-Frt cassette was inserted 982 bp 5'-upstream of exon 21 and a loxP site placed 557 bp 3'downstream of the same exon. The selection cassette was removed via FLP-mediated recombination in the germline. Subsequent Cre-mediated recombination in the germline removed exon 21. |
