4G8_SPKYG_570_beta-amyloid_Antibody_041020
IHC staining of Spark YG™ 570 anti-β-Amyloid, 17-24 antibody (clone 4G8) on formalin-fixed paraffin-embedded Alzheimer's disease brain tissue. Following antigen retrieval using 88% formic acid, the tissue was incubated with 2 µg/mL of the primary antibody overnight at 4°C. The slide was mounted with fluoromount G with DAPI. The image was captured with a 40X objective. Scale bar: 50 µm

Description

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.

Application

IHC-P - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 2.0 - 10 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

* Spark YG™ 570 has a maximum excitation of 555 nm and a maximum emission of 570 nm.

Excitation Laser
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
Application Notes

This antibody is reactive to amino acid residues 17-24 of ß amyloid. The epitope lies within amino acids 18-22 of ß amyloid (VFFAE). 4G8 ß-amyloid antibody reacts to abnormally processed isoforms, as well as precursor forms.

This antibody clone has been reported for use on IHC of free-floating sections in PBS containing 1% Triton incubated with 0.1 m citrate buffer (4).

Additional reported applications (for the relevant formats) include: immunohistochemical staining on frozen tissue sections (IHC-F) and immunocytochemistry (ICC)

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.
