title: [Preparation of polyclonal antibody to human prion protein using the expressed GST-PrP fusion protein as antigen].
abstract: OBJECTIVE
  Preparing specific antibody to prion protein.
  
  
  METHODS
  Using prokaryotic expressed GST-PrP fusion protein as antigen, rabbits were immunized subcutaneously.
  
  
  RESULTS
  ELISA assay revealed that the titer of the prepared antiserum against expressed PrP protein was as high as 1:128 000. Western blot test showed that the antiserum was able to react with the in vitro expressed intact and different lengths of C-terminus truncated PrP proteins, as well as the native PrP proteins from brain homogenization of human and mouse.
  
  
  CONCLUSIONS
  The prokaryotic expressed GST-PrP fusion protein can efficiently elicit in immunized animals the PrP-specific antibody.
