Revvity, 62B40PEG, HTRF Amyloid β1-40 Detection Kit

Overview
Amyloid ß1-40 and ß1-42 peptides are involved in the appearance of Alzheimer's disease symptoms. The production of these two amyloid peptides is regulated by the activity of 2 enzymes, ß and γ secretase, which cleave the amyloid precursor protein. This kit is intended to measure amyloid ß1-40 peptides in cell supernatant or in whole cells. This assay is a fast alternative to ELISA, thanks to the ease-of-use of our Add and Read method.
HTRF assays offer many advantages over other technologies:
Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
How it works
Assay principle
The HTRF Amyloid ß1-40 assay is a sandwich immunoassay using two monoclonal antibodies that recognize different epitopes within the ß1-40 peptide. One antibody is labelled with Eu3+-Cryptate and the other with XL-665. The assay can be used with whole cells or cell supernatant.
Assay protocol
The Amyloid ß1-40 assay features a streamlined protocol with only two incubation steps:
- Cell stimulation by target compounds
- Amyloid ß1-40 detection using HTRF reagents
The antibodies labelled with HTRF donor and acceptor may be pre-mixed and added in a single dispensing step to further speed up the assay procedure. This protocol requires a single 24-hour incubation at 4°C following cell stimulation.
