abstract = {The development of the real-time quaking-induced conversion
(RT-QuIC), an in vitro protein misfolding amplification
assay, was an innovation in the scientific field of protein
misfolding diseases. In prion diseases, these types of
assays imitate the pathological conversion of the cellular
prion protein (PrPC) into a protease-resistant and/or
amyloid form of PrP, called PrP resistant (PrPRes). The
RT-QuIC is an automatic assay system based on real-time
measuring of thioflavin-T (Th-T) incorporation into amyloid
fibrils using shaking for disaggregation. It has already
been applied in diagnostics, drug pre-screening, and to
distinguish between different prion strains. The seeded
conversion efficiency and the diagnostic accuracy of the
RT-QuIC assay strongly depend on the kind of recombinant PrP
(rec PrP) substrate. The DNA sequences of different
substrates may originate from different species, such as
human, bank vole, and hamster, or from a combination of two
species, e.g., hamster-sheep chimera. In routine use, either
full-length (FL) or truncated substrates are applied which
can accelerate the conversion reaction, e.g., to a more
sensitive version of RT-QuIC assay. In the present review,
we provide an overview on the different types of PrP
substrates (FL and truncated forms), recapitulate the
production and purification process of different rec PrP
substrates, and discuss the diagnostic value of CSF RT-QuIC
in human prion disease diagnostics.},
