title: An efficient procedure for purification of recombinant human β heat shock protein 90.
abstract: OBJECTIVE
  Heat Shock Protein 90 (Hsp90) is typically the most abundant chaperone in the eukaryotic cell cytoplasm, and its expression is essential for loading immunogenic peptides onto major histocompatibility complex molecules for presentation to T-cells. Therefore, it may act as a good candidate as an adjuvant molecule in vaccine technology.
  
  
  METHODS
  Initially the human Hsp90β gene was cloned into the heat inducible expression vector pGP1-2 and then the recombinant protein was isolated by ion exchange chromatography. After intradermal injection of confirmed purified band of protein to rabbits and isolation of the serum IgG antibody, for its affinity purification, the rabbit's purified Hsp90 specific IgG was coupled to the cyanogen bromide-activated Sepharose 4B.
  
  
  RESULTS
  The recovery of the purified protein of interest by affinity chromatography was 50%.
  
  
  CONCLUSIONS
  This research enabled purification of human heat shock protein by a laboratory prepared column chromatography.
