Background InformationAmyloid beta A4 protein (UniProt P05067; also known as ABPP, Alzheimer disease amyloid protein, Amyloid precursor protein, APP, APPI, Cerebral vascular amyloid peptide, CVAP, PN-II, PreA4, Protease nexin-II) is encoded by the APP (also known as A4, AD1) gene (Gene ID 351) in human. Amyloid precursor protein (APP) is initially produced with a signal peptide sequence (a.a. 1-17), the removal of which yields the mature protein with a large extracellular portion (a.a. 18-699), followed by a transmembrane segment (a.a. 700-723) and a cytoplasmic (a.a. 724-770) tail. APP can be further processed by the α-, β-, and γ-secretases in two alternative processing pathways. In the non-amyloidogenic pathway, APP is first cleaved by the plasma membrane-localized α-secretase to generate an N-terminal extracellular sAPPα fragment (a.a. 18-687) and a membrane-bound C-terminal fragment C83 (CTFα), which can be further cleaved by γ-secretase to produce a non-toxic small peptide p3 and a cytoplasmic APP intracellular domain (AICD). In the amyloidogenic pathway, APP undergoes β-cleavage in BACE-1 (β-site APP-cleaving enzyme)-enriched endosomes to generate an N-terminal extracellular sAPPβ fragment (a.a. 18-671) and a membrane-bound C-terminal fragment C99 (CTFβ). Subsequent cleavage of C99 by γ-secretase releases the amyloid β peptides, Aβ1-42 (672-713) & Aβ1-40 (672-711), and AICD. Aβ accumulation in the cortical and hippocampal regions of the brain is a major pathological feature of Alzheimer's disease (AD). Aβ Ser8 phosphorylation is shown to promote Aβ aggregation into oligomeric and fibrillar assemblies and to prevent Aβ proteolytic clearance by certain proteases.

  • Immunohistochemistry
  • Immunofluorescence
Application NotesWestern Blotting Analysis: 2 µg/mL from a representative lot detected 2.5-100 ng of Ser8-phosphorylated synthetic Aβ1-40 peptide, but not non-phosphorylated Aβ1-40 peptide (Courtesy of Dr. Kumar and Prof. Dr. Walter, Department of Neurology, University Bonn, Germany).
Western Blotting Analysis: 2 µg/mL from a representative lot detected phosphorylated oligomeric amyloid beta (pAβ) peptides in 50 µg of brain extract from an 8-month old APP/PS1KI transgenic mouse, but not in extract from an age-matched non-transgenic mouse (Courtesy of Dr. Kumar and Prof. Dr. Walter, Department of Neurology, University Bonn, Germany).
ELISA Analysis: Clone 1E4E11 hybridoma culture supernatant detected the immunogen peptide with phosphorylated Ser8, but not the corresponding non-phosphorylated peptide (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709).
Immunohistochemistry Analysis: A representative lot detected age-dependent phospho-amyloid beta (pAβ) immunoreactivity and localization in paraffin-embedded APP/PS1KI mouse brain sections following antigen retrieval by heat and 88% formic acid treatments (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709).
Immunofluorescence Analysis: A representative lot detected phospho-amyloid beta (pAβ) immunoreactivity in cortical neurons colocalized with that detected with a non-phospho-specific Aβ antibody by dual fluorescent immunohistochemistry staining of paraffin-embedded 2-month old APP/PS1KI mice cotex sections following anigen retrieval by heat and 88% formic acid treatments (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709).
Western Blotting Analysis: A representative lot detected monomeric, dimeric, trimeric, and oligomeric forms of synthetic Aβ1-40 and Aβ1-42 peptides with phosphorylated Ser8, but not the non-phosphorylated Aβ1-40 and Aβ1-42 peptides (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709).
Western Blotting Analysis: A representative lot detected monomeric, dimeric, and oligomeric forms of phosphorylated amyloid beta (pAβ) peptides in brain extracts from 6- and 12-month old APP/PS1KI transgenic mice, but not in brain extracts from age-matched non-transgenic mice (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709).
Note: Formic acid (88%) treatment following heat retrieval is recommended for immunohistochemical detection of aggregated intraneuronal Abeta peptides in brain sections (Kumar, S., et al. (2013). Acta Neuropathol. 125(5):699-709; Christensen, D.Z., et al. (2009). Brain Res. 1301:116-125).
