Figure 1From: Caspase-mediated cleavage of actin and tubulin is a common feature and sensitive marker of axonal degeneration in neural development and injury Demonstration of specificity of caspase cleavage neoepitope antibodies to actin and tubulin. In vitro cleavage of the substrates was performed via incubation of either recombinant active caspase-3 or −6 with permeabilized brain-derived synaptosomes. A western blot was performed using lysate from this preparation. Blot (a) was colabeled with general anti-alpha-tubulin (tubulin, red) and TubulinΔCsp6 (Cleaved-Tub, green). Blot (b) was colabeled with anti-actin (red) and anti-fractin (green). Recombinant cleaved-caspase-3 (rCC3) generates both cleaved tubulin (a) and fractin (b), whereas recombinant cleaved-caspase-6 (rCC6) only generates only cleaved tubulin (a).Back to article page
