Semi-automatic protein crystallization system that allows in situ observation of X-ray diffraction from crystals in...

Semi-automatic protein crystallization device was developed using 96 format Hydra dispenser. Eight extra syringes were added for pipetting protein solution with its own dispensing mechanism. This device allows setting up 96 drops in about three minutes. New crystallization plate has also been developed. The plate allows collecting an oscillation photograph of the crystal directly in the drop. The diffraction quality of the crystals in the drops can be inspected without causing any other physical perturbations to the crystals. With the modified dispenser and this plate, we can perform both hanging and sitting drop vapour diffusion method.
