The transgene is composed of a 1.9-kb rat AGT cDNA coupled to a 5.8-kb mouse alpha-MHC gene promoter. 1.6 kb of the rabbit bIVS2 intronic sequences are also included. RT-PCR analysis indeicated that this transgene was expressed specifically in the heart. Five copies of the transgene are integrated in TG153 transgenic mice. (J:129140)
