Safe method for isolation of prion protein and diagnosis of transmissible spongiform encephalopathies

Provided is a safe novel method for detecting Transmissible Spongiform encephalopathies (TSE). The method comprises: selecting a sample from a subject to determine whether the subject has transmissible spongiform encephalopathy; and detecting abnormal prion protein (Prpes) in the sample. The method detects PrPres without Proteinase-K treatment by disrupting the sample in guanidine thiocyanate lysis solution followed by phenol purification of proteins, and demonstration of the abnormal prion isoform by Western blotting using monoclonal antibodies against prion protein structure. Guanidine salts effectively kill TSE infectivity providing a laboratory safe environment and stabilize biomolecules so TSE samples can be procured in the field and transported to the laboratory in guanidine lysis solution for processing at a later date. This method provides for rapid detection of the abnormal prion isoform diagnostic of TSE and results are easily interpretable based upon very different Western blot patterns for abnormal prion isoform versus the normal prion.
