1VAPOR DIFFUSION, HANGING DROP7.5298Ammonium sulphate,crystals were grown after the protein was reductively alkylated. All QacR-drug complexes were crystallized in this manner. Although not required, only small crystals are obtained otherwise and take several months to grow., pH 7.5, VAPOR DIFFUSION, HANGING DROP, temperature 298K
