Quantitative analysis of the kinetics of intramitochondrial membrane potential (ΔΨm) and mitochondrial [Ca2+]m changes in C2C12 WT and PV-clones after KCl-induced depolarization.

Results are from at least 3 independent myotube preparations and number of cells analyzed ranged from 6–16 per genotype (WT and PV-clones) and conditions (100# and 300# mM KCl; *p#The concentrations represent values of the added solutions to the perfusion chamber. The actual concentration sensed by the cells is assumed to be at least 2-fold lower.
