      Background InformationOne of the most important and initial steps which causes loss of memory and cognition in Alzheimer’s Disease (AD) involves proteolytic cleavage of amyloid precursor protein (APP, chromosome 21) releasing short 40, 42 & 43 amino acid peptides (Amyloid Beta) 1-40, 1-42 and 1-43). Polymerization of beta-amyloid and subsequent neuronal deposit (amyloid) leads to the degeneration of neurons involved in memory and cognition.
      Product Information
      • Human Alzheimer's brain tissue.
      PresentationPurified mouse monoclonal IgG1κ in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.
      ApplicationAnti-Amyloid Beta (ABeta) x-42, clone 12F4 is an antibody targeting the Amyloid Beta (ABeta) x-42 protein, validated for use in IHC & ELISA.
      Key Applications
      • Immunohistochemistry
      • Enzyme Immunoassay (ELISA)
      Application NotesImmunohistohemistry Analysis: A 1:500 dilution from a representative lot detected Amyloid Beta (ABeta) x-42 in human pons/midbrain tissue.

      ELISA Analysis: A representative lot detected Amyloid Beta (ABeta) x-42, but demonstrates a loss of signal against Amyloid Beta (ABeta) x-42.

      Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Amyloid Beta (ABeta) x-42, but demonstrated a loss of signal against x-40 and not x-43 in WB (Prof. J. Buxbaum, Mt. Sinai School of Medicine).
      Biological Information
      ImmunogenKLH-conjugated linear peptide corresponding to human Amyloid Beta (ABeta) x-42.
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis antibody detects Amyloid Beta (ABeta) x-42, but does not cross react with Amyloid Beta (ABeta) x-40 or Amyloid Beta (Abeta) x-43.
