Basal [Na+]i Values in Jewell-Lingrel Cell Lines
| Isoform transfected | Basal [Na+]i | n | ||
|---|---|---|---|---|
| None | 18.6 ± 4.6 | 5 | ||
| α1 | 11.5 ± 5.6 | 3 | ||
| α2 | 13.4 ± 2.7 | 6 | ||
| α3 | 50.3 ± 6.0 | 7 | 
Basal [Na+]i values were determined in untransfected HeLa cells and in HeLa-based Jewell-Lingrel cell lines. Values are in millimolars. The value for the α3-transfected cells is significantly different (P < 0.05) from those for the other cell lines by ANOVA (Scheffé multiple comparison test).
