  1. Intra-assay imprecision: three conditioned media samples from three different experiments were tested ten times on one plate.
  2. Inter-assay imprecision: the same samples were tested three times in three independent assays. Mean ± SEM of r-sAPPα concentration (ng/ml). CV: coefficient of variation (%).
