Abstract: Most investigations on biological macromolecules are important for the knowledge of the functions in living organisms. Nowadays it is well known that the three-dimensional structure of proteins is obtained either by NMR or X-ray crystallographic methods. The crucial part in the latter is the availability of high- quality crystals in order to perform structural characterization. Nevertheless, there are some approaches to overcome this problem from the statistical [ Jancarik and Kim, J. Appl. Crystallogr. 24 (1991) 409] and physico-chemical point of view [Ries-Kautt and Ducruix, Methods in Enzymology 276 Part A, Ch. 3, 1997, p. 23]. Once the crystals are obtained, the following part of of the protein system should be taken into account in order to avoid a sedimentation phenomena and how the crystal growth technique is determined in order to keep the same diffusion pattern throughout the experiment.
