The adduct was then crystallized by using the hanging drop vapour diffusion method. Drops of 1 microliter were prepared at room temperature mixing 0.5 microliter of adduct at concentration 15 mg/mL with an equal amount of a reservoir constituted by 1.1 M NaCl, 0.1 M acetate buffer, pH 4.0. Crystals of the adduct grow within 24-48 hours. PH range: 4
