The CAG promoter drives ubiquitous expression of a floxed lacZ/STOP cassette followed by the mouse coding sequencem IRES and EGFP. Cre-mediated recombination removed the lacZ/STOP cassette and allows for the expression of the mouse cDNA and EGFP. Lines 1 and 2 were generated. The pound symbol (#) is used when no line is specified and/or lines are pooled. (J:164198)
