1 | VAPOR DIFFUSION, HANGING DROP | 4.2 | 295 | Crystallization of PSD-93 PDZ1ext was performed using the hanging-drop vapor diffusion technique by mixing 1 microliter of a 2 mg/ml protein solution (PBS buffer) and 1 l reservoir solution (0.2 M lithium sulfate, 20% PEG 1000, 0.1 M citric acid/sodium hydrogen phosphate pH 4.2. The reservoir volume was 500 microliter, VAPOR DIFFUSION, HANGING DROP, temperature 295K |
