Revvity, AL3204HV, AlphaLISA Human and Mouse Total HTT Detection Kit, 100 Assay Points

Overview
Huntingtin (HTT) is a cytoplasmic protein which is highly expressed in the brain, and whose anti-apoptotic role is critical for neuronal survival. The wild-type (WT) protein has a functional structure, with a "normal" polyglutamine (polyQ) domain containing less than 36Q. The mutant HTT protein harbors an abnormally long polyQ tract (> 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.

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
How it works
Principle of the AlphaLISA human and mouse HTT assay
The AlphaLISA Huntingtin (HTT) assay is based on an AlphaLISA sandwich immunoassay involving a biotinylated anti-HTT antibody bound to Streptavidin-coated AlphaLISA Donor beads and an anti-HTT antibody conjugated to AlphaLISA Acceptor beads. Both antibodies are directed against the HTT protein. In the presence of the HTT, both antibodies bind to HTT and the beads come into proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer within the Acceptor beads, resulting in emission with λmax at 615 nm. The intensity of the signal is directly proportional to the concentration of HTT present in the sample (cell cell lysate or tissue lysate).

Protocol of the AlphaLISA human & mouse Total HTT assay
The AlphaLISA Total HTT assay can be run in a 96- or 384-well detection plate (50 µL final). As described here, samples (cell lysates or tissue lysates) or control lysate are dispensed directly into the assay plate for the detection of HTT by AlphaLISA reagents. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally.
