Equilibrium values of [Ca2+]m at rest and during nerve stimulation
| Rhod-FF/Rhod-5N | Mito-D4cpv | Mito-TN-XXL | |
|---|---|---|---|
| Rest | — | — | 0.22 ± 0.04 |
| 30 Hz | 13.1 ± 3.9 | — | — |
| 42 Hz | 24.3 ± 3.4 | 27.0 ± 2.6 | — |
| 60 Hz | 35.4 ± 10.0 | — | — |
| 80 Hz | 44.3 ± 6.4 | 62.9 ± 4.9 | — |
Nerves were stimulated at various frequencies, and equilibrium values were derived from measurements using Ca2+ indicators rhod-FF/5N, D4cpv, and TN-XXL. Values are shown as the mean ± SE (μM).
