IHC staining of Biotin anti-β-Amyloid, 17-24 antibody (clone 4G8) on formalin-fixed paraffin-embedded human Alzheimer's disease brain tissue. Following antigen retrieval using 70% formic acid for 20 minutes at room temperature, the tissue was incubated with 1 µg/ml of the primary antibody for 60 minutes at room temperature. For detection, the HRP labeling reagent and DAB from BioLegend Ultra Streptavidin (USA) HRP Detection Kit were used (Multi-Species, component #5, DAB; Cat. No. 929901). Slides were counterstained with hematoxylin, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 µm

    Direct ELISA of Biotin anti-β-Amyloid, 17-24 (clone 4G8) antibody binding to the plate-immobilized human Aβ1-40, human Aβ1-42, and recombinant human APP751 protein. ELISA was performed by coating the wells with 100 ng of peptide or recombinant protein. The wells were then incubated with the primary antibody at 37°C for 45 minutes followed by incubation with HRP labeled streptavidin. TMB (3, 3', 5, 5' tetramethylbenzidine, Cat. No. 421501) was used as the detection system.

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
Direct ELISA - Validated

Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 2.0 µg/ml is suggested. For Direct ELISA applications, a concentration range of 0.5 - 2.0 µg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody is reactive to amino acid residues 17-24 of β amyloid. The epitope lies within amino acids 18-22 of β amyloid (VFFAE). 4G8 β-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.
