--> PerkinElmer - Cisbio Home HTRF technology Basics HTRF® technology Basics The simpler way to get your work done HTRF Assay Principle HTRF (Homogeneous Time Resolved Fluorescence) is a no-wash technology. It combines standard FRET technology with time-resolved measurement of fluorescence, eliminating short-lived background fluorescence. For a sandwich assay, two antibodies that recognize a protein of interest are used, with one antibody coupled to a donor, and the other with the acceptor. If the 2 antibodies recognize the analyte, the donor will emit fluorescence upon excitation and the energy will be transferred to the nearby acceptor, giving specific acceptor fluorescence. The donor fluorescence is also measured and a ratio with the acceptor fluorescence is applied. femme_ipad Never wash a well again, use HTRF How HTRF technology assays work The HTRF protocol is simple and straightforward. It requires few steps: First add your analyte or sample to your microplate, then add the detection reagents: Anti-analyte conjugated donor and acceptor conjugated antibody. Incubate 2 hours (up to overnight for some assays). The assay is then ready to be read on an HTRF compatible or certified microplate reader. The emission of light by the acceptor will be proportional to the level of interaction. How HTRF can simplify your life Benefit from more than 350 ready-to-use kits that contain everything you need, and take advantage of this easy solution that saves you both time and money. Rapid, homogeneous, easy to use and to automate, allowing extreme miniaturization and easy assay development – over recent years, HTRF has become the gold reference for time-resolved FRET. Easy to implement Saves time Scalable No washing required HTRF is expanding research possibilities for a growing number of applications HTRF has been proven in a variety of applications including GPCRs, kinases, epigenetics, PPIs and the quantification of a wide range of biomarkers including cytokines.
