The mutant HTT protein harbors an abnormally long polyQ tract (\u0026gt; 36Q) which causes the aggregation of the no longer functional protein. HTT aggregation leads to the selective neuronal cell death responsible for Huntington's Disease.\u003cbr\u003e\nHTRF assays offer many advantages over other technologies:\u003c\/p\u003e\n\n\u003cp\u003eHomogeneous add-and-read format\u003cbr\u003e\nNo wash steps\u003cbr\u003e\nLow background\u003cbr\u003e\nStraightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates\u003cbr\u003e\nStable signal, providing flexibility in time of readout or size of assays\u003cbr\u003e\nHow it works\u003cbr\u003e\nPrinciple of the HTRF Human \u0026amp; Mouse Aggregated HTT assay\u003cbr\u003e\nThe HTRF Aggregated HTT assay is based on a TR-FRET sandwich immunoassay involving two specific antibodies, one labelled with Tb3+-cryptate (donor) and the other with d2 (acceptor). One antibody is directed against the N-terminal part of the protein, and the second recognizes specifically the aggregated form. Both antibodies bind to aggregated HTT, and the donor-acceptor proximity enables a fluorescent TR-FRET signal to occur. The intensity of the signal is directly proportional to the level of HTT aggregates present in the sample (cell lysate or tissue lysate).\u003c\/p\u003e\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\u003cp\u003e \u003c\/p\u003e\n\n\n\u003cp\u003eProtocol of the HTRF Human \u0026amp; Mouse Aggregated HTT assay\u003cbr\u003e\nThe HTRF Aggregated HTT assay can be run in a 96- or 384-well low volume white detection plate (20 µL final). As described here, samples (cell\/tissue lysates) are dispensed directly into the assay plate for the detection of HTT aggregates by HTRF reagents. The antibodies labelled with HTRF fluorophores may be pre-mixed and added in a single dispensing step. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally.
