Crude extracts of SBY625/pRS426 (lanes 1-3), SBY625/p2509 (lanes 4–6), W303-1A (lane 7), SBY625 (GLC7-HA3) (lanes 8, 9), JC1552-17A (lane 10), JC1535 (lane 11), JC746-9D/YCp50 (lane 12), JC746-9D/YCp50-HA-GLC7 (lane 13), JC1338-20A/YCp50 (lane 14), and JC1338-20A/YCp50-HA-GLC7 (lane 15) were separated by SDS-PAGE, blotted and probed with anti-HA or anti-Pgk1 antibodies. All lanes except lane 9 have 20 µg protein,which has 10 µg. All cultures except those in lanes 7–11 were grown in minimal medium; those in lanes 7–11 were grown in YEP-glucose. The pRS426 and p2509 transformants (lanes 1–6) were induced with the indicated final concentration of CuSO4 during the last two hours of growth. The Glc7/Pgk1 ratio was calculated from film densitometry.
