Biolegend, 856503, Alexa Fluor® 647 anti-β-Amyloid, aggregated Antibody, 25μg

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.

Structure: 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, and 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.
Interaction: Tau, prion, α2-macroglobulin, apoE and apoJ, toll-like receptor 2 (TLR2), TLR4, TLR6, and their co-receptors CD14, CD36, and CD47.
Ligand/Receptor: Receptor for advanced glycation end products (RAGE), low-density lipoprotein receptor-related protein 1 (LRP1), glycoprotein 330 (gp330/megalin), P-glycoprotein.
