The authors regret that in the original version of their paper, some of the values given in the KRB solution were incorrect. The corrected subsection of the Materials and methods appears below in its entirety:

Drugs and solutions

All tissues were perfused and maintained with KRB solution containing (mmol/liter): 120.35 NaCl, 15.5 NaHCO₃, 5.9 KCl, 1.2 MgCl₂, 1.2 NaH₂PO₄, 2.5 CaCl₂, and 11.5 glucose. The KRB solution warmed to a physiological temperature of 37 ± 0.2°C and bubbled with a mixture of 97% O₂–3% CO₂. For experiments using external solutions with zero [Ca²⁺]_o, CaCl₂ was omitted and 1 mM EGTA was added to the solution. NNC 55-0396 and TTA-A2 were purchased from Alomone Labs, nicardipine was purchased from Sigma-Aldrich, thapsigargin, isradipine, and ryanodine were purchased from Tocris Bioscience, and multiple batches of Xestospongin C (XeC) were purchased from Cayman Chemical.

All versions of this article have been corrected.
