Fig. 1. The construct for transgenic activation of Pax6. The
construct pJoP6 contains the ß-actin/CMV fusion promotor and a
loxP-flanked gfp-stop cassette placed in front of the
Pax6 and lacZ coding sequences. After Cre-mediated
recombination, the gfp-stop cassette is eliminated allowing
simultaneous expression of transgenic Pax6 and lacZ via an
IRES sequence from the resulting construct pJoP6rec. Arrows indicate
the annealing sites of the primers JoP6F and JoP6R.
