Huntington's disease is caused by a gain-of-function neurotoxic mutation in normally neuroprotective huntingtin. Sensitive assays are required to discriminate mutant huntingtin from wild-type huntingtin. We have developed a normalized 384-plate assay for determination of mutant and wild-type huntingtin. Based on a single pipetting step, the sensitive assay uses two antibody pairs for simultaneous mutant and wild-type huntingtin time-resolved fluorescence resonance energy transfer detection combined with PicoGreen quantification of double-stranded DNA. The assay can be used for discovery of drugs reducing mutant huntingtin over wild-type huntingtin and for assessing the value of huntingtin as a disease progression marker, and it is adaptable to other proteins of interest.
