Specificity / Sensitivity
β-Amyloid (1-43) (E8C2D) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total human Aβ-43 protein. This product detects transgenically expressed human APP in mouse models. This antibody weakly cross-reacts with human Aβ-42 protein.
Species Reactivity:
Human
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Mouse
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy of human β-Amyloid (1-43) protein.
Background
Amyloid β (Aβ) precursor protein (APP) is a 100-140 kDa transmembrane glycoprotein that exists as several isoforms (1). The amino acid sequence of APP contains the amyloid domain, which can be released by a two-step proteolytic cleavage (1). The extracellular deposition and accumulation of the released Aβ fragments form the main components of amyloid plaques in Alzheimer's disease (1). APP can be phosphorylated at several sites, which may affect the proteolytic processing and secretion of this protein (2-5). Phosphorylation at Thr668 (a position corresponding to the APP695 isoform) by cyclin-dependent kinase is cell-cycle dependent and peaks during G2/M phase (4). APP phosphorylated at Thr668 exists in adult rat brain and correlates with cultured neuronal differentiation (5,6).
Aβ43 has been suggested as a biomarker in early onset of Alzheimer's disease, where patients have lower levels of Aβ43 in cerebrospinal fluid (7,8,9). Several studies have shown that Aβ toxicity of Aβ43 is as high as Aβ42 or Aβ40 in different models of Alzheimer's disease, including mouse models and human disease. (10).
