| 1 | VAPOR DIFFUSION, HANGING DROP | 4.5 | 293.15 | Protein: 5.4 mg/ml NTM in 10 mM HEPES, pH 8.0, 150 mM sodium chloride Reservoir Solution: 2.5 M NaCl, 100 mM sodium acetate pH 4.5, 200 mM lithium sulfate Crystallization Drop: 2 micro-Liters NTM + 2 micro-Liters Reservoir Solution Single crystals grew to a size of ~250 x 150 micro-meters within 7-10 days. Crystals harvested from the crystallization drops were cryo-protected in reservoir solution containing 20% (v/v) ethylene glycol and then flash cooled by plunging into liquid nitrogen |
