Poly18058_PURE_beta-Amyloid_011020_update.png
Western blot of purified anti-mouse/rat β-Amyloid antibody (Poly18058). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain lysate; Lane 3: 20 µg of mouse brain lysate; Lane 4: 20 µg of rat brain lysate. The blot was incubated with 1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP donkey anti-rabbit IgG antibody (Cat. No. 406401). Enhanced chemiluminescence was used as the detection system.

Description

Amyloid beta (Aβ or Abeta) denotes peptides of 36–43 amino acids in length that are crucially involved in Alzheimer's disease as the main component of the amyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is cut by certain enzymes to yield Aβ. Aβ molecules can aggregate to form oligomers (known as "seeds")  which are believed to be able to induce other Aβ molecules to also take the misfolded oligomeric form, leading to a chain reaction akin to a prion infection. The seeds or the resulting amyloid plaques are toxic to nerve cells. The other protein implicated in Alzheimer's disease, tau protein, also forms such prion-like misfolded oligomers, and there is some evidence that misfolded Aβ can induce tau to misfold.

Concentration
1.0 mg/mL
Storage & Handling
Do not store antibody diluted below 50 ug/mL in the absence of protein (i.e.: add 2% bovine serum albumin). The antibody solution should be stored undiluted between 2°C and 8°C. Please note the storage condition for this antibody has been changed from -20°C to between 2°C and 8°C. You can also check your vial or your CoA to find the most accurate storage condition for this antibody.
Application

WB - Quality tested
IHC-F, ELISA - Reported in literature

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 1.0 - 10.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

BioLegend’s rabbit anti-Amyloid beta is specific for the Aβ. The rabbit anti-rodent Aβ reacts extremely well with all isoforms. The rabbit anti-rodent Aβ antibody has been reported to have negligible cross-reactivity to human Aβ using immunohistochemistry.

This product may contain other non-IgG subtypes.

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, 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.
