Surface-Sarcolemmal and T-Tub Caveolar Dimensions in Intact Ventricular Tissue
| Caveolae Type | Longest Axis Length (nm) | Volume (nm3) | Surface (nm2) |
|---|---|---|---|
| Surface-sarcolemmal caveolae (n = 45) | 77.4 ± 2.42 | (276 ± 19) × 103 | (20.32 ± 0.02) × 103 |
| T-tub caveolae (n = 64) | 73.9 ± 2.38 (n.s.) | (244 ± 19) × 103 (n.s.) | (19.75 ± 0.01) × 103 (n.s.) |
Data are from reconstructions. n.s., no significant difference between surface-sarcolemmal and T-tub caveolae.
