Anti-Beta (β)-Amyloid antibody

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.
