1 | VAPOR DIFFUSION, SITTING DROP | 295 | SMYD3 crystallization and soaking of GSK2807: SMYD3 (1-428) expressed in baculovirus and with SAH in the SAM-binding site was crystallized in sitting drops at 22C using 1uL fresh protein at 8.9mg/mL with the addition of 1uL mother liquor (200mM MgOAc Tetrahydrate, 20% PEG 3350). Crystals grew to a large size but varied in quantity when set up in replicates. A seed stock was formed from these crystals and added at 20% to the mother liquor solution prior to plate setup. Crystals of large size were then created with 1.3uL protein and 1.3uL of mother liquor containing seeds in a sitting drop MRC-2 plate (Hampton Research). Crystal nucleation occurred overnight and reached maximum size in 4 days |
