Een<em> In vitro</em> Werkwijze voor de bereiding functionele glucocorticoid receptor (GR) • hsp90 eiwitcomplexen uit gezuiverde eiwitten en cellulaire lysaten wordt beschreven. De methode maakt gebruik van immunoadsorption van recombinant GR, gevolgd door zout-strippen en eiwitcomplex reconstitutie. Het belang van co-factoren en de buffer omstandigheden worden besproken, evenals potentiële methode toepassingen.
