Production of A 40 and A 42 peptides under ASP-RNAi. The pAPP695SWE (A-C) plasmid and both the pAPP695SWE and pAPP695WT (D-F) plasmids together with the indicated siRNA duplexes against the Swedish mutant were cotransfected into Cos-7 cells, and expressed sAPP polypeptide and A 40 and A 42 peptides in culture media were examined by western blotting (A, D) and ELISA (B, C, E, F), respectively. “Vector” indicates cells transfected with only plasmid(s). Endogenous and exogenous (expressed) sAPPs are indicated by asterisks and arrow heads, respectively. ELISA data are averages of three independent determinations. Error bars represent standard deviations.
