Abstract
The invention relates to a method for isolating nucleic acid molecules which are capable of specific interaction with native PrPSc and can differentiate between native PrPc and native PrPSc. The inventive method comprises the following steps: incubating a pool of nucleic acids with purified PrPSc preparations (PPPs); selecting and isolating the resulting protein/nucleic acid complexes and optionally amplifying the specific nucleic acids, in addition to optionally repeating the incubation and isolation stage. The invention also relates to the nucleic acid molecule produced by this method and the use thereof for diagnosing and treating transmissible spongiform encephalopathies.
