HTRF
HTRF®, an assay technology developed by Cisbio, combines standard FRET (fluorescence resonance energy transfer) with time-resolved measurement of fluorescence, eliminating short-lived background fluorescence. HTRF’s applications include assessment of small phosphorylated peptides, immunoassays for quantifying large glycoproteins, and indirect detection of tagged complexes such as CD28/CD86 via secondary antibodies. These homogeneous assays do not require wash steps and are amenable to small-volume microplate formats used in high-throughput screening.
(This assay is suitable for SpectraMax® iD5 and SpectraMax® Paradigm readers.)
