Model Description
A SA-2xpolyA-CAG-LSL-EGFR(T790M-del19)-IRES-luciferase-2A-tdTomato-WPRE-polyA cassette was inserted at the Rosa26 locus. When bred to a strain expressing Cre recombinase under control of various tissue specific promoters, Cre recombination deletes the LSL cassette and allows the expression of the EGFR(T790M-del19) protein.
