Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 6.9 293 Crystals of beta-Lactoglobulin were grown using 3.0 M (NH4)2SO4, 0.1 M sodium/potassium phosphate buffer pH 6.9 as reservoir. Protein crystallizes at a concentration of 18 mg/mL. Crystals of beta-Lactoglobulin were soaked in a solution consisting of 3.0 M (NH4)2SO4, 0.1 M sodium/potassium phosphate buffer (pH 6.9) with 5 mM CDDP (about 1:3 protein to metal ratio).
