Description générale

Amyloid β-peptide (Aβ), a 38 to 43 amino acid peptide is obtained from the β-amyloid precursor protein (APP). β-amyloid gene is located on human chromosome 21q21. APP is a type I transmembrane protein. It is produced in the endoplasmic reticulum (ER) and then migrated with the help of Golgi apparatus to the trans-Golgi-network (TGN).
The β-amyloid precursor protein (APP) is cleaved sequentially by the proteolytic enzymes β-secretase (BACE1) and γ-secretase to produce β-amyloid (Aβ) peptides with the Aβ1-42 and the Aβ1-40 forms being the most prevalent. Secreted Aβ peptides are degraded either via a re-uptake mechanism followed by endosomal degradation, or by an extracellular insulin degrading enzyme. Extracellular accumulation of Aβ leads to the formation of aggregates, fibrils and eventually amyloid deposits called neuritic plaques, which is the hallmark of Alzheimer′s disease (AD).
The antibody recognizes human β-amyloid peptide, full-length amyloid precursor protein (APP), soluble-APP (sAPPβ′ and sAPPα), C99 cleavage form, and Aβ (1-40/42), but not soluble-APP form sAPPβ.

Immunogène

synthetic peptide corresponding to amino acids 1-11 of human β-amyloid protein.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Monoclonal Anti-β-Amyloid antibody has been used in the titration of IgG1 and IgG2a isotype antibodies. It has also been used in the synthesis of antibody-functionalized magnetic nanoparticles.
Mouse Monoclonal Anti-β-Amyloid antibody has been used for western blot assays. The product can also be used for immunohistochemistry, immunoprecipitation, indirect ELISA and microarray studies.

Actions biochimiques/physiologiques

β-amyloid gene acts as the substrate of insulin-degrading enzyme (IDE). It plays a major role in the pathogenesis of Alzheimer′s disease (AD) and type 2 diabetes mellitus (DM2).

Description de la cible

Amyloids are insoluble protein aggregates consisting of misfolded proteins and peptides. Amyloid deposition are associated with multiple neurodegenerative disorders.

Forme physique

Mounting evidence suggests that both C-terminal extensions and N-terminal truncations help precipitate amyloid plaque formation. Although mechanisms underlying the increased generation
