Revvity, 62ESTPEG, HTRF Estradiol Detection Kit, 500 Assay Points

Overview
There is substantial research indicating that breast cancer tissue contains the enzymes necessary to synthesize estradiol (17ß-estradiol), a steroid hormone that plays an important role in this disease. Two main pathways are involved in the formation of estradiol in breast cancer tissues: the aromatase pathway, which transforms androgens into estrogens, and the sulfatase pathway, which converts estrone into estradiol via the 17ß-HSD1 enzyme. The Estradiol kit is a highly specific assay for measuring estradiol in cell supernatants, or biochemical enzyme assays.
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 kit is based on a competitive format involving a specific antibody labelled with Cryptate (donor) and estradiol coupled to XL665 (acceptor). Estradiol produced by cells or purified 17ß-HSD1 enzyme competes with XL665-labelled estradiol for binding to monoclonal anti-estradiol Eu Cryptate.

Assay protocol
The estradiol assay features a streamlined protocol with only two incubation steps: - Cell stimulation by target compounds - Estradiol detection using HTRF reagents This protocol requires only a single, two-hour incubation period following cell stimulation. Application-Protein Quantification
