Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 6.5 293 VEGFA-121 from Peprotech, catalogue number 100-20A, was mixed at a 1:1 molar ratio to VEGF monomer. The complex was concentrated to 11 mg/ml. Crystallization involved hanging drop vapour diffusion against 0.1 M MES pH 6.5 and 1.6 M magnesium sulphate. Crystals grew in about 120 days and were frozen in liquid nitrogen with 20 % glycerol as cryoprotectant.
