A sensitive and quantitative assay for measuring cleavage of presenilin substrates.

Abstract excerpt

The presenilin (PS) proteins are components of the gamma-secretase activity, which is central in the pathogenesis of Alzheimer's disease. Here we present a novel cell-based reporter gene assay for the quantification of PS-controlled gamma-secretase cleavage of the Alzheimer amyloid precursor protein (APP). We show that this assay offers several advantages, including increased sensitivity and specificity, improved...
