Abstract
An assay comprises contacting cells containing a conformationally altered protein with test compound and determining if the altered protein is cleared. The cells may be scrapie-infected neuroblastoma cells. Another assay comprises contacting organ or tissue homogenate (at pH 5.0 or less) with test compound to determine if altered protein in the homogenate is cleared. The homogenate may be brain homogenate from a transgenic mouse infected with human prions. Compounds which are found to clear the altered protein are useful in preventing, arresting and/or reversing (i.e. treating) a disease associated with the conformationally altered protein.
