IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, SITTING DROP7293Crystals were grown from protein solution mixed with an equal volume of reservoir solution, 0.5% Jeffamine, 100 mM HEES pH 7.0, and 1.1 pM Sodium Malonate H 7.0 (Hampton Index HT screen: C9) in a SD2 format microplate set with a TTP Labtech Mosquito robot. Crystals were cryoprotected with 1.0% Jeffamine, 100 mM HEES pH 7.0, 1.1 M Sodium Malonate pH 7.0, and 20% ethylene glycol
