A transgenic construct containing the mutant mouse androgen receptor (Ar), wild-type, under the control of the minimal -426/+28 rat probasin promoter, a rabbit beta-globin sequence fragment, a bovine growth hormone polyadenylation site sequence and an N-terminal hemagglutinin (HA) epitope tag was injected into fertilized FVB/N mouse eggs. Three lines were generated and no line numbers were given. (J:96117)
