Western blots of AβPP and N- and C-terminal related peptides. A) The amounts of AβPP holoprotein (110 kDa) and 28 and 25 kDa bands are increased in all PSEN mutations relative to the ND controls. The 110 kDa (AβPP) in SAD is almost equivalent to the ND cases, but is variable with respect to the 28 and 25 kDa bands. B) In our SDS-PAGE system the CT99 and CT83 co-migrate as a single band at ~14 kDa. As can be appreciated, the ND controls have significantly less CT peptides than the PSEN and SAD cases. In addition, AβPP (110 kDa) was variable between the PSEN cases and the ND controls, but was decreased in the SAD cases compared to the ND controls. SAD = sporadic Alzheimer's disease; ND = non-demented.
