Rapid, high-throughput detection of PrP^Sc by 96-well immunoassay

Prion diseases are emerging infectious disorders that affect several mammalian species including humans. The transmissible agent is comprised of PrP^Sc, a misfolded isoform of the normal host-encoded prion protein PrP^C. Immunodetection of PrP^Sc 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 PrP^Sc. This assay has PrP^Sc 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.
