Testing method for Alzheimer's disease by measuring the rate of degradation of beta-amyloid in blood and diagnostic reagent

摘要

Method for testing Alzheimer's disease, comprising a peptide metodoariadir said p-amyloid 1-42 in a blood sample, on the P-amyloid 1-42 quo means P-amiloidehumano comprises 42 amino acids and wherein the Oland 1-42 ° 0-amyloid includes a site aescindirse quo is a degrading enzyme, measuring a residual amount of the peptide p-amyloid 1-42 afiadido the blood sample by uninmunoensayo sandwich double antibody, they use a quo quo antibody recognizes a site Cterminaldel peptide p-amyloid 1-42 quo will afiadirse the blood sample and an antibody as quoreconoce N-terminal thereof, site to measure a degradation activity * Tido p-amyloid 1-42 the blood sample, and comparing the degradation activity measured with the blood of normal subjects.
