Comparison of the Volumes of Junctional Ca2+ Compartments and [CSQN]SRrl among the Models

SJ Model LC Model SM Model HuVEC Model
Vds or Vjnc in the HuVEC model 0.002–0.005a pL/cell 0.0486–0.1215a pL/cell 0.013–0.033a pL/cell 0.303 pL/cell
1.0 × 10−7 pL for each d.s. 2.43 × 10−6 pL for each d.s. cleft height 30 nm, (7 × 30)2 nm2 area for each d.s. 0.8% Vcell
VSRrl 0.2–0.5a pL/cell 0.08–0.21a pL/cell 0.14 pL/cell 0.46 pL/cell
1.0 × 10−5 pL for each CaRU 4.21 × 10−6 pL for each CaRU 0.35% Vcell assumed in the HuVEC model 1.2% Vcell
[CSQN]SRrl 10.0 mM 30.0 mM 30.0 mM 3 mM
VSRup infinite 3.5% Vcell 3.5% Vcell 4.8% Vcell

In the Hinch model, 50,000 CaRUs/cell and 2 × 10−7 pL/d.s. were assumed.
