1	VAPOR DIFFUSION, SITTING DROP	7.5	277	CFTR NBD1 V510D in buffer A was crystallized by mixing equal amounts of protein at 6 mg/mL with 0.1 M Tris pH 7.6, 28% (w/v) polyethylene glycol 10,000. Crystallization was induced by streak-seeding using crystals grown in 0.1 M HEPES, pH 7.5, 25% (w/v) polyethylene glycol 550 monomethylether, and plates incubated at 4C. Crystals grew over several days and were frozen by quick dip in reservoir solution supplemented with 25% (w/v) ethylene glycol
