The following elements comprise the transgene insert (derived from VectorBuilder plasmid VB180522-1028tgr): 5' PiggyBac ITR (inverted terminal repeat), CAG promoter, mouse Gm40600 cDNA, rat beta globin poly(A) signal sequences, and the 3' ITR. The sequence was inserted using the PiggyBac transposon system. (J:311878)
