E. Traces showing average changes (mean±s.e.m.) in intracellular Ca2+ (Fura 2 ratio) in primary astrocytes after transfection with non-silencing (siCTL, black trace, n=216) or exonA-specific siRNA (siS1A, red trace, n=263). Data information: Data were obtained from three biological replicates (e.g. transfections) with each three measured dishes (technical replicates) with multiple cells each (yielding a total number n) and is shown as mean±s.e.m.
