Webb11 jan. 2024 · Conceptually analogous to the polymerase chain reaction (PCR) for DNA, PMCA is based on the principle of mixing PrPC substrate molecules with small amounts of brain- or cell-derived PrPSc particles, and subjecting the sample to consecutive cycles of sonication and incubation. Group Leader Prof. Joaquin Castilla, PhD WebbPrion diseases are a group of neurodegenerative disorders that infect animals and humans with proteinaceous particles called prions. Prions consist of scrapie prion protein (PrPSc), a misfolded version of the cellular prion protein (PrPC). During disease progression, PrPSc replicates by interacting with PrPC and inducing its conversion to PrPSc.
