    • 7 cpm/ml in hybridization buffer: 66% formamide, 260 mM NaCl, 1.3x Denhardt solution (13 mM tris, pH 8.0, 1.3 mM EDTA, 13% dextran sulfate). Sections in the hybridization mixture were covered with siliconized glass cover slips and sealed with DPX mountant. After the slides had been incubated at 58°C for 20 hours, they were soaked in 4x SSC to remove cover slips, then rinsed in 4x SSC (four times, 5 min each) before treatment with ribonuclease A (20 mg/ml for 30 min at 37°C). The slides were then rinsed in decreasing concentrations of SSC containing 1 mM dithiothreiotol (DTT) to a final stringency of 0.1 x SSC, 1 mM DTT for 30 min at 65°C. After the sections had been dehydrated in increasing concentrations of ethanol, they were vacuum-dried and exposed to DuPont Cronex-4 x-ray film for 7 days. The film was scanned by a Microtek ScanMaker 1850S at a resolution of 728 pixels per centimeter, and the images were analyzed with Image v1.55 software (NIH) and Photoshop (Adobe).

    • After establishment of the two-electrode voltage clamp, the oocyte was impaled with a third electrode containing 200 mM EGTA, pH adjusted to 7.2 with KOH. We monitored the input resistance during impalement to ensure oocyte viability. At the indicated time, 50 nl of the EGTA solution was injected into the oocyte. If we assume an oocyte volume of 1 μl, the predicted final concentration of EGTA was 10 mM.
