General description

Amyloid beta A4 protein, also known as ABPP or APPI (APP) or Alzheimer disease amyloid protein or Cerebral vascular amyloid peptide (CVAP) or PreA4 or Protease nexin-II (PN-II), and encoded by the gene name APP or A4 or AD1, belongs to the APP family. The beta-amyloid peptide (beta A4), proteolytically released from the amyloid precursor protein (APP), is the principal component of senile plaques in Alzheimer′s disease. Cleavage of APP by alpha-secretase or alternatively by beta-secretase leads to generation and extracellular release of soluble APP peptides, S-APP-alpha and S-APP-beta, respectively, and the retention of corresponding membrane-anchored C-terminal fragments, C83 and C99. Subsequent processing of C83 by gamma-secretase yields P3 peptides. This is the major secretory pathway and is nonamyloidogenic. Alternatively, presenilin/nicastrin-mediated gamma-secretase processing of C99 releases the amyloid beta proteins, amyloid-beta 40 (Abeta40) and amyloid-beta 42 (Abeta42), major components of amyloid plaques, and the cytotoxic C-terminal fragments, gamma-CTF(50), gamma-CTF(57) and gamma-CTF(59). Mab βA4N-1E8 recognizes the free N-terminus of the bA4 polypeptide with high preference and crossreacts with sAPPα.

Specificity

This antibody is specific for the first 2 amino acids of the Amyloid beta peptide amino terminus.

Immunogen

Epitope: N-terminus
KLH-conjugated peptide corresponding to the N-terminus of human Amyloid βA4.

Application

Immunohistochemistry Analysis: A 1:500-2,000 dilution from a representative lot was used to detect Amyloid βA4 in human Alzheimer′s brain and thalamus tissues.

Western Blotting Analysis: A representative lot was used to detect Amyloid βA4 in Western Blotting. (Wiltfang, et al. 2001; Serneels, et al. 2009; Maler, et al. 2007).

Immunoprecipitation Analysis: A representative lot was used to detect Amyloid βA4 in Immunoprecipitation. (Wiltfang, et al. 2001; Maler, et al. 2007).
