IHC staining of purified anti-β-Amyloid, aggregated antibody (clone A18114B) on formalin-fixed paraffin-embedded Alzheimer’s disease brain tissue. Following antigen retrieval using formic acid, the tissue was incubated with 0.5 µg/mL of the primary antibody overnight at 4°C. BioLegend’s Ultra Streptavidin (USA) HRP Detection Kit (Multi-Species, DAB, Cat. No. 929901) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 µm -
IHC staining of purified anti-β-Amyloid, aggregated antibody (clone A18114B) on formalin-fixed paraffin-embedded Alzheimer’s disease brain tissue.

Western blot of purified anti-β-Amyloid, aggregated antibody (clone A18114B). Lane 1: Molecular weight marker; Lane 2: 20 µg of Tris buffer (pH 7.4) extract from Alzheimer’s disease brain; Lane 3: 20 µg of Tris buffer (pH 7.4) extract from normal human brain; Lane 4: 20 µg of Tris/2% SDS buffer extract from Alzheimer’s disease brain; Lane 5: 20 µg of Tris/2% SDS buffer extract from normal human brain; Lane 6: 100 ng human APP751 recombinant protein. The blot was incubated with 10 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP goat anti-mouse IgG antibody (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.

Alzheimer's disease is characterized by the accumulation of aggregated Aβ peptides in senile plaques and vascular deposits. Aβ peptides are derived from amyloid precursor proteins (APP) through sequential proteolytic cleavage of APP by β-secretases and γ-secretases generating diverse Aβ species. Aβ can aggregate to form soluble oligomeric species and insoluble fibrillar or amorphous assemblies. Some forms of the aggregated peptides are toxic to neurons.

Antigen Details
- Structure
- Amyloid precursor protein is a 770 amino acid protein with a molecular mass of ~100 kD. According to the UniProtKB database, APP (ID# P05067) has 11 isoforms (34 to ~90 kD) and the 770 form has been designated as the canonical form. Isoform APP695 is the predominant form expressed in neuronal tissue. Isoforms APP751 and APP770 are widely expressed in non-neuronal cells. Isoform APP751 is the most abundant form in T-lymphocytes. Aβ denotes peptides of 36-43 amino acids generated from cleavage of APP by secretases. Aβ has an apparent molecular mass of about 4 kD.
- Distribution
-
Tissue distribution: Primarily nervous system, but also adipose tissue, intestine, muscle.
Cellular distribution: Cytosol, endosomes, nucleus, plasma membrane, extracellular, and Golgi apparatus. - Function
- The normal function of Aβ is not well understood. Several potential physiological roles have been proposed, including: activation of kinase enzymes; protection against oxidative stress; regulation of cholesterol transport; transcription factor, and as an anti-microbial agent.
