beta Amyloid Antibody (MOAB-2)

Immunohistochemistry: beta Amyloid Antibody (MOAB-2) [NBP2-13075] - IHC analysis of beta Amyloid on normal mouse brain (left) and 5xFAD mouse brain (right) using DAB with hematoxylin counterstain. The MOAB-2 antibody was used at 1:20 on normal mouse brain and at 1:400 on 5xFAD mouse brain.

Background

Beta Amyloid, also known as Abeta, is a peptide that varies in length from 39 to 43 amino acids and is processed from the Amyloid precursor protein (APP). Beta Amyloid is known as the main component of amyloid plaques, which are deposits found in the brains of patients with Alzheimer's disease. The form(s) of beta Amyloid associated with the pathology characteristic of Alzheimer's disease still remains unclear. Currently, controversy exists as to the existence of intraneuronal beta Amyloid. Research indicates that intraneuronal beta Amyloid accumulation may be an important proximal neurotoxic event in the pathogenesis of Alzheimer's disease. Many commercially available beta Amyloid antibodies cross react with APP or APP C-terminal fragments. This MOAB-2 antibody is specific for beta Amyloid but not APP. MOAB-2 is a pan-specific beta Amyloid antibody that detects unaggregated, oligomeric and fibrillar forms of beta Amyloid. This is important because beta Amyloid is known to aggregate and form a variety of potentially toxic conformations. MOAB-2 displays strong extracellular beta Amyloid immunoreactivity, and so detects classic plaque pathology. MOAB-2 is selective for Abeta 42 over Abeta 40. This is also an advantage as the 42 amino acid form of beta Amyloid is likely the toxic form. MOAB-2 demonstrates strong intraneuronal immunoreactivity in both human and beta Amyloid-Tg mouse tissue and has the potential to aid future research into the functional importance of intraneuronal beta Amyloid.
