Catalog Proteins - Prions

Prion proteins (PrPs) for study of transmissible spongiform encephalopathies (TSEs).

These recombinant proteins are expressed in E. coli, then purified and refolded. Hamster and bank vole sequences are available, and both are active in Real-Time Quaking-Induced Conversion assays (RT-QuIC).
