Igs37^{tm1(ACTB-EGFP,-tdTomato)Biat}

The GT MADM targeting construct was designed with a CMV enhancer/chicken beta-actin core promoter (pCA), the N-terminal portion of a mutant enhanced green fluorescent protein (mut4-EGFP; aa 1-273), a beta-globin intronic sequence containing an FRT site and loxP-flanked neomycin resistance gene, the C-terminal portion of a red fluorescent protein (tdTomato; aa 4-1544) tagged with three copies of the Myc epitope at its C-terminus, and an SV40 T-antigen poly(A) signal. This entire GT MADM construct was inserted into the "Hipp16" locus on chromosome 16 (between Gm5767 and Usp7). (J:306183)
