The purified HSA was dissolved in 20 mM potassium phosphate (pH 7.0) and concentrated to 120 mg/mL. To the HSA solution we added 10 mM cpdX and 3 mM myristate, dissolved DMSO. The final concentration of DMSO was 5% (v/v). The crystal was grown by the hanging drop vapor diffusion method using a reservoir solution containing 50 mM sodium-potassium-phosphate (pH 7.0), and 30% polyethylene glycol 3350. For crystallization 1 uL of HSA/cpdX solution was equilibrated against 1 uL of reservoir solution. After about one-week, colorless crystals appeared.
