Anti-Amyloid Antibody, β 1-40

The cerebral and vascular plaques associated with Alzheimer′s disease (AD) are mainly composed of amyloid beta peptides (Ab). Ab is derived from cleavage of the amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. Ab [1-40], Ab [1-42], and Ab [1-43] peptides result from cleavage of APP after residues 40, 42, and 43, respectively. The cleavage takes place by gamma-secretase during the last APP processing step. Ab [1-40], [1-42] and [1-43] peptides are major constituents of the plaques and tangles that occur in AD. Ab antibodies and peptides have been developed as tools for elucidating the biology of AD.

Recognizes beta-amyloid 1-40. One of the most important and initial steps which causes loss of memory and cognition in Alzheimer′s Disease (AD) involves proteolytic cleavage of amyloid precursor protein (APP, chromosome 21) releasing short 40, 42 & 43 amino acid peptides (beta amyloid 1-40, 1-42 and 1-43). Polymerization of beta-amyloid and subsequent neuronal deposit (amyloid) leads to the degeneration of neurons involved in memory and cognition. The immunogen peptide shows homology with beta-amyloid 1-28 and beta-amyloid 12-28. No cross reactivity is observed with CGRP.

A 7 amino acid peptide sequence from the C terminus of human beta-amyloid 1-40.
