AMYLOID MEASUREMENT METHOD

摘要

Disclosed herein is an A² measurement method capable of accurately measuring the concentration of A² in a sample even when the sample contains a very low level (about several pM) of A². The amyloid ² measurement method includes: a sample preparation step 101 in which a sample possibly containing amyloid ² is placed in a sample treatment vessel; a concentration step 102 in which a solubilizer that solubilizes amyloid ² is added to the sample in the sample treatment vessel and the amount of solvent contained in the sample is reduced; a neutralization step 103 in which the solubilizer in a treated sample solution obtained in the concentration step is neutralized; and a measurement step 104 in which amyloid ² possibly contained in a neutralized treated sample solution is quantitatively measured based on an antigen-antibody reaction.
