Selection of transgenic mouse lines. (A) Analysis of PG-1 transgene copy number in transgenic founder mice. Data shown are the means ± SEMs from triplicate experiments. (B) Comparison of PG-1 transgene expression level in the respiratory tract tissues among different transgenic mouse lines. Four to six transgenic mice were analyzed for each line, and data shown are the means ± SEMs. Values of the same tissue labeled with different lower case letters are significantly different at P < 0.05. NG no germline transmission of transgene, IF infertile.
