Figure Lengend Snippet: Cell death characteristics in cell culture. Top: Morphological characteristics of apoptotic and necrotic cell death (left: membrane “blebbing” and apoptotic bodies in apoptosis, right: increase in cell volume and membrane rupture in necrosis). Middle: Caspase-8 and -3 activation in apoptosis versus no activation in necrosis in triplicates. Bottom: cfDNA fragment sizes in base pairs (bp) related to sample intensity (normalized FU) (left: nucleosomal laddering in apoptosis, right: “smear” in necrosis, middle: influence of DNase1 on cfDNA released by apoptosis and necrosis, red: apoptosis, blue: necrosis, grey: negative control. Color should be used in print.
Article Snippet: Western blot analysis was conducted to detect apoptosis through caspase-8 and -3 activation (Caspase-8 (1C12) Mouse mAb 9746, Cell Signaling; Caspase-3, 31A1067, NB100-56708, Novus Biologicals, both 1/1000) (n = 60 cell culture samples, including cell pellets for western blots and cell culture supernatant for cfDNA analysis).
Techniques: Cell Culture, Membrane, Activation Assay, Negative Control
