The Centre of Molecular Structure in IBT CAS (BIOCEV, Vestec, Czech Republic) is the complex of scientific core facilities focused on Structural Biology. Among the others, it includes a core facility, devoted entirely to the crystallization of biomacromolecules and their complexes. Diffraction analysis of single crystals is one of the main approaches in structural biology and this facility is equipped with all instruments necessary for crystallization experiments. The equipment includes robots that automatically set up high-throughput crystallization experiments in plates, as well as with crystallization hotels, that can monitor and screen the crystallization process using several techniques. One of the latest improvements to this facility is the SONICC instrument (Formulatrix comp.). It is connected to the RI1000 crystallization hotel and enables screening of experiments using SHG (Second Harmonic Generation) and UV-TPEF (Ultraviolet Two-Photon Excited Fluorescence). This allows the detection of microcrystals and even nanocrystals, which is essential for various methodical approach
