1	MICROBATCH		292	Crystallization buffer was prepared by mixing a solution containing 100 mM MES-NaOH, pH 6.0, 100 mM NaOAc, 8% PEG 10K and an additive solution (20% acetonitrile, 5% n-Dodecyl-?-D-maltoside) in a 5:1 (v:v).Microbatch drops were formed by mixing 1.8 ?l of the crystallization buffer with 1.2 ?l of the preformed complex
