Figure 2.
The immature APP isoforms accumulating under NSC48478 are acetylated. Total cell lysates were immunoprecipitated with an anti-APP antibody and then analysed for both APP (upper panel) and anti-acetylated lysine (lower panel) antibodies. Only the immature APP isoforms are acetylated (arrowheads). Beads alone indicate the negative control of the IP (immunoprecipitate). Asterisks (around 100 kDa) point to a specific band deriving from anti-acetylated lysine antibody hybridization. L: cell lysate; SN: supernatant.
