摘要: A clone encoding PrP 27-30, the major protein in purified preparations of scrapie agent, was selected from a scrapie-infected hamster brain cDNA library by oligonucleotide probes corresponding to N terminus protein. Southern blotting with revealed single gene same restriction patterns normal and DNA. PrP-related also detected murine human mRNA found at similar levels brain, as well many other tissues. Using antisera against crude extracts infected lesser extent brain. Proteinase K digestion yielded 27-30 extract, but completely degraded extract. No nucleic acids were prions, indicating that is not encoded acid carried within infectious particles.
