Both proteins were purified and concentrated to 20 mg/ml in buffer containing 25 mM Tris, pH 7.2, 150 mM NaCl, 1 mM TCEP, 0.5 mM EDTA. The proteins were mixed in a 1:2 molar ratio (CAPN7:IST1). Crystals grew at 21 C (294 K) in Rigaku Wizard Cryo condition D5 (25% (v/v) 1,2-Porpanediol, 100 mM Sodium phosphate dibasic/Citric acid pH 4.2, 5% (w/v) PEG 3000, 10% (v/v) Glycerol. Crystals were transferred briefly to crystallization buffer supplemented with 25% added glycerol prior to plunging in liquid nitrogen |
