For immunocytochemistry assays, myotubes were fixed in cold methanol (−20 °C) for 30 min and permeabilized with 0.05% Tween 20 in PBS for 1 min, as previously described [7 (link),8 (link),16 (link),17 (link)]. For immunoblot assays, solubilized lysate of myotubes (15 μg of total protein) was subjected to SDS–PAGE (8 or 10% gel), as previously described [7 (link),8 (link),16 (link),17 (link),18 (link),19 (link),20 (link)]. Anti-RyR1 and anti-SERCA1a antibodies were obtained from Affinity BioReagents. Anti-DHPR, anti-Orai1, anti-STIM1, and anti-α-actin antibodies were obtained from Abcam (Cambridge, MA, USA).
