Perfusion data for study 2
| Perfusion conditions | Number of tubules studied | Mean luminal Hg2+ concentration | Content of Hg2+ in TCA-soluble tubule fraction | Content of Hg2+ in TCA-insoluble tubule fraction | Leak | |
|---|---|---|---|---|---|---|

| None | 20 μm Hg2+ | 3 | 0.24 ± 0.20 | 1.00 ± 0.51 | 6845 ± 1767 | 9.03 ± 5.10 |
| None | 20 μm Hg2+ + 200 μmDMPS | 3 | 0.46 ± 0.12 | 3.32 ± 3.98 | 30.7 ± 16.12-a | 0.33 ± 0.062-a |
Values represent the mean ± standard error obtained from isolated perfused S2 segments of proximal tubules. Refer to Materials and Methods for details of the experimental design.
