  • Patent number: 7741054
    Abstract: The invention is directed to a method for performing a high throughput test to determine the presence of PrPsc in a tissue sample taken post mortem from brain, the test comprising the workflow of (A) sample preparation, (B) sample treatment, (C) sample analysis, (D) controls, and (E) classifying the results of the analysis as positive or negative. The invention is further directed to preparing a treated biological sample suspected of containing PrPsc such that it is suitable for specific detection of PrPsc, if present, the method comprising the steps of (a) homogenizing the sample; followed by (b) digesting the sample proteolytically by adding to the homogenate Proteinase K and incubating the sample; followed by (c) adding a peptidic protease inhibitor to the incubated mixture of step (b), thereby obtaining a treated biological sample suitable for specific detection of PrPsc, if present. The invention further provides a conditioned microwell plate.

  • Patent number: 7442497
    Abstract: Methods for determining chronic hepatitis C infection are provided by the present invention. The methods generally involve determining the optical density of fluid samples which have tested positive for hepatitis C infection using an antibody-based assay. The optical density can then be used to determine in a predictive or probability-based manner whether the fluid sample contains chronic hepatitis C infection or whether the fluid sample merely contains antibodies to hepatitis C infection without resorting to costly molecular detection methods. Thus, the present invention permits differentiation between individuals who have cleared hepatitis C infection but still test positive in an antibody-based assay from individuals having chronic hepatitis C infection.
