A method for extracting prion protein from a biological material, e.g., an animal tissue or product. In a specific example, abnormal prion protein is extracted from homogenized sheep brain with hexafluoro-2-propanol. The hexafluoro-2-propanol is separated from the aqueous brain preparation by increasing the ionic strength of the aqueous solution. Prion protein in the organic extract can be further purified, or the extract can be tested, e.g., by immunoassay, for the presence of prion protein, and more particularly abnormal prion protein. The extraction process permits testing for the presence of abnormal prior protein, e.g., for diagnosis of transmissible spongiform encephalopathies (TSE).

The “discrete frequency stir” (DFS) method provides improved mode stir testing of electromagnetic characteristics of an enclosure/cavity. Adequate sampling of the electric field inside the enclosure/cavity is provided by electronic perturbation or stirring of the field with a short duration, continuous wave, radiated source where the wave frequency is stepped in small steps across a frequency range of interest. The frequency steps are selected to be at least slightly larger than the resonant mode bandwidth associated with the given enclosure/cavity in order to provide statistically independent measurements. A stirring bandwidth is selected to encompass a statistically significant number of these measurement samples while maintaining adequate frequency resolution. A statistical evaluation of the measured field is then performed over this stirring bandwidth. For example, the average field level at a given frequency is determined by averaging over the samples contained within the stirring bandwidth when centered on that frequency.
