| molecularNote | A targeting construct was designed to insert an frt-EGFP-loxP sequence upstream of exon 1 and a loxP-PGK-frt downstream of exon 2 such that cre mediated excision would remove the exons while allowing EGFP expression and, alternatively, FLP-mediated excision would remove both the exons and the EGFP. |
