Product Type Specific: APP pan-specific antibody
Antibody Code: NN192-3
Antibody Target Type: Pan-specific
Protein UniProt: P05067
Protein SigNET: APP
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Synthetic peptide patterned after human APP
Antibody Immunogen Sequence: CKMDAEFRHDSGYEVHHQKL
Antibody Immunogen Description: Corresponds to amino acid residues K670 to L688.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Amyloid monomeric proteins can sometimes oligomerize into destructive amyloid fibrils. Amyloidogenic conformations of non-disease related proteins can be created by partial protein misfolding or denaturation. Many degenerative diseases are known to be related to the accumulation of misfolded proteins as amyloid fibres (1, 2). These include the amyloid-β peptide plaques and tau neurofibrillary tangles in senile plaques of Alzheimer’s symptomology, the deposition of α-synuclein in the Lewy bodies of Parkinson’s disease, and accumulation of polyglutamine-containing aggregates in Huntington’s disease (2, 3). Amyloid Precursor Protein (APP) is a type-I transmembrane glycoprotein, primarily expressed in the brain, that plays a critical role in synaptic formation, repair, and neuronal signaling. It is the precursor to the amyloid-beta (Ab) peptide, which, when misprocessed, forms pathogenic amyloid plaques in Alzheimer's disease. Abnormal cleavage of APP by beta-secretase and gamma-secretase releases toxic peptides, which aggregate into neurotoxic extracellular plaques. APP features a large extracellular N-terminal domain, a single transmembrane domain, and a short intracellular C-terminal domain (AICD). It is normally highly expressed in the nervous system, and is involved in cell adhesion, copper transport, synaptic plasticity and long-term potentiation.
