Figure 2. Puromycin- and thapsigargin-evoked calcium leakage activates SOCE. Typical [Ba2+]c traces in response to puromycin 200 µM (A) and thapsigargin 1 µM (B) under control conditions and after pretreatment with 200 µM anisomycin or BEL 25 µM (C, D). E) Cumulative data (mean±SEM) for the normalized rate of barium increase.
