1-11-3_PURE_B-Amyloid_Antibody_IHC_062818
IHC staining of purified anti-β-Amyloid, x-42 antibody (clone 1-11-3) 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 5 µg/ml of the primary antibody overnight at 4°C. BioLegend´s Ultra-Streptavidin (USA) HRP 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

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 protein (APP) through sequential proteolytic cleavage of APP by β- 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.

Storage & Handling
This antibody should be handled aseptically as it is free of preservatives such as Sodium Azide. Store this antibody 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 the vial label or CoA to find the proper storage conditions.
Application

IHC-P - Quality tested
WB - Reported in the literature, not verified in house
Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5.0 - 10 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody is effective in immunohistochemistry (IHC-P) and immunoblotting (WB).

This antibody is reactive to the C-terminus of beta amyloid and specific for the isoform that ends at the 42nd amino acid.
