Does Scrapie Agent Contain DNA or RNA? An assay was developed to transfer scrape from sheep extracts to mice. This assay took a very long time to complete. It was subsequently shown that Syrian Hamsters are more sensitive hosts, and in fact there is a species barrier to transmission. Exposing scrapie extracts to UV or [...]
