title: Reference materials for the evaluation of pre-mortem variant Creutzfeldt-Jakob disease diagnostic assays.
abstract: OBJECTIVE
  A standard panel of materials is needed for the evaluation of assays being developed for the diagnosis of variant Creutzfeldt-Jakob disease.
  
  
  METHODS
  Tissues from human and animals incubating transmissible spongiform encephalopathy disease have been prepared, aliquoted and where possible characterized by in vitro methods.
  
  
  RESULTS
  A standardized preparation of materials has been generated.
  
  
  CONCLUSIONS
  Large-scale preparations of tissues and blood fractions can be used to directly compare the sensitivities of assays using different formats.
