Expression of globin mRNA in transgenic mice containing the BGT131 (mOct-1 ATR) construct.

S1 nuclease protection analysis on day 15.5 fetal liver RNA reveals expression of the γ-globin transgene 3/3 single-copy and 7/7 multicopy animals to a mean of 31% of each endogenous mouse β^major-globin gene. Abbreviations are as described in the legend to Figure 6.
