Anti-Beta (β)-Amyloid antibody

The β/A4 amyloid precursor protein (APP) is a transmembrane glycoprotein and exists in three isoforms. This protein is composed of a single-pass transmembrane domain, a large extracellular N-terminal domain, and a short cytoplasmic C-terminal tail. The APP gene is located on the human chromosome at 21q21.3-q22.

110/120/130 kDa

Epitope: a.a. 66-81 of APP {N-terminus}

Purified recombinant Alzheimer precursor A4 (pre A4695) fusion protein.

Anti-APP A4 Antibody, a.a. 66-81 of APP , clone 22C11 has been used in immunohistochemistry and immunoblotting(1:1000).

Anti-APP A4 Antibody reacts with pre-A4 and recognizes amino acids 66-81 of the N-terminus on the pre-A4 molecule (Hilbich et al., 1993). 22C11 recognizes all three isoforms of APP, immature ~110kDa, sAPP ~120kDa, and mature ~130kDa (Hoffmann et al., 2000). The Anti-APP A4 antibody is known to cross-react with APLP2 (Slunt, 1994).

The β/A4 amyloid precursor protein (APP) undergoes proteolytic cleavage and produces β/A4 peptide. The extracellular deposition of this peptide is observed in brain cortical parenchyma and cerebro-meningeal blood vessels which marks the pathological condition of Alzheimer′s disease. Mutations of the APP gene lead to the early onset of Alzheimer′s disease and hereditary cerebral hemorrhage with amyloidosis.
