Protein misfolding cyclic amplification assay
WebbIn contrast to other in vitro misfolded protein amplification assays-such as protein misfolding cyclic amplification (PMCA)-which are based on sonication, the RT-QuIC technique is based on prion seed-induced misfolding and aggregation of recombinant prion protein substrate, accelerated by alternating cycles of shaking and rest in fluorescence ... WebbSeeding activity is usually detected using either a real-time quaking-induced conversion (RT-QuIC) or protein misfolding cyclic amplification (PMCA). Both are seed amplification assays (SAAs), based on the observation that misfolded aSyn in patient biospecimens can induce conformational change and aggregation of recombinant aSyn in vitro, ...
