Mouse monoclonal antibody [4H308] to beta Amyloid (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.

Tested Applications
IHC-PWB
WB: 1/1000. Detects a band of approximately 4.5 kDa (predicted molecular weight: 4.5 kDa). IHC-P: 1/250 detects amyloid b in human brain sections. Optimal dilutions/concentrations should be determined by the end user.
Recognizes amyloid bx-40 polypeptide, Mr 4.5kD. At dilution of 1/1000 detects 1microgram of synthetic amyloid b1-40 polypeptide, but not amyloid b1-42 and 1-43.
Cellular Localization
Type I membrane protein.
