Rapid, high-throughput detection of PrPSc by 96-well immunoassay

Prion diseases are emerging infectious disorders that affect several mammalian species including humans. The transmissible agent is comprised of PrPSc, a misfolded isoform of the normal host-encoded prion protein PrPC. Immunodetection of PrPSc is often utilized for prion disease diagnosis and tracking spread of the infectious agent through the host. We have developed a rapid, high-throughput 96-well immunoassay, which is specific for the detection of PrPSc. This assay has PrPSc detection limits similar to western blot and is advantageous because of its comparatively shorter running time, smaller start-up and operation costs and large sample capacity.
