BCL2L1 and neuroblastoma: c-mAbs allow the immuno-detection of intracellular Bcl-xL amyloid aggregates following apoptosis induced by metal stress in SH-SY5Y cells : we then investigated if c-mAbs were suitable for both detecting Bcl-xL aggregates and characterizing these aggregates, in neuroblastoma cells under iron stress (Figure 5).
