Crystallization

Equipment

Tecan Genesis
work station is used for dispensing mother liquor solutions in the crystallization well reservoir (100-150µl) and setting up high volume crystallization trials (0.5µl to 2µl).

Cartesian Microsys
is used to set up low volume crystallization drops in plates prefilled by the Tecan robot. Routinely, volumes of 100 nl are used for both the protein and the precipitant.

 

A Mosquito®
robot from TTP LabTech’s for nanolitre pipetting, making use of disposable positive displacement pipettes for the elimination of cross contamination. The robot automates protein crystallography set-ups (hanging drop, sitting drop and microbatch techniques) and additive screening. This provides an ideal set up for our systematic proteolytic cleavage during crystallogenesis strategy (Collinet et al., 2011).

RockImager 182 and 1000 (Formulatrix)
After preparation of the crystallization trays, these are stored in a crystallization cabinet equipped with a robotized visualization system (Rockimager 182, Formulatrix) that at regular intervals takes pictures of the crystallization drops and stores them on computer for inspection.
